### Possible Issue 1: Unable to call save endpoint from CDN/static server
If you're running Dashy using a static hosting provider (like Vercel), then there is no Node server, and so the save config action will not work via the UI.
You'll instead need to copy the YAML after making your changes, and paste that into your `conf.yml` directly. If you've connected Vercel to git, then these changes will take effect automatically, once you commit your changes.
Look here for more information: [https://dashy.to/docs/deployment#deploy-to-cloud-service](https://dashy.to/docs/deployment#deploy-to-cloud-service)
If you're running on Netlify, there are some cloud functions which take care of all the server endpoints (like status checking), so these will work as expected.
See also [#1465](https://github.com/Lissy93/dashy/issues/1465)
In Docker, double check that the file isn't read-only, and that the container actually has permissions to modify it. You shouldn't really be running it as a root user, and I'm not sure if it will work if you do-
After saving, the frontend will recompile, which may take a couple seconds (or a bit longer on a Pi or low-powered device). If it doesn't recompile, you can manually trigger a re-build.
As defined in [RFC-7034](https://datatracker.ietf.org/doc/html/rfc7034), for any web content to be accessed through an embedded element, it must have the [`X-Frame-Options`](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/X-Frame-Options) HTTP header set to `ALLOW`. If you are getting a `Refused to Connect` error then this header is set to `DENY` (or `SAMEORIGIN` and it's on a different host). Thankfully, for self-hosted services, it is easy to set these headers.
These settings are usually set in the config file for the web server that's hosting the target application, here are some examples of how to enable cross-origin access with common web servers:
In Apache, you can use the [`mod_headers`](https://httpd.apache.org/docs/current/mod/mod_headers.html) module to set the `X-Frame-Options` in your config file. This file is usually located somewhere like `/etc/apache2/httpd.conf
If you're seeing Dashy's 404 page on initial load/ refresh, and then the main app when you go back to Home, then this is likely caused by the Vue router, and if so can be fixed in one of two ways.
The first solution is to switch the routing mode, from HTML5 `history` mode to `hash` mode, by setting `appConfig.routingMode` to `hash`.
If this works, but you wish to continue using HTML5 history mode, then a bit of extra [server configuration](/docs/management.md#web-server-configuration) is required. This is explained in more detaail in the [Vue Docs](https://router.vuejs.org/guide/essentials/history-mode.html). Once completed, you can then use `routingMode: history` again, for neater URLs.

## 404 On Multi-Page Apps
Similar to above, if you get a 404 error when visiting a page directly on multi-page apps, then this can be fixed under `appConfig`, by setting `routingMode` to `hash`. Then rebuilding, and refreshing the page.

For more info, see [Issue #1](https://github.com/Lissy93/dashy/issues/1)
First of all, check that you've got yarn installed correctly - see the [yarn installation docs](https://classic.yarnpkg.com/en/docs/install) for more info.
If you're getting an error about scenarios, then you've likely installed the wrong yarn... (you're [not](https://github.com/yarnpkg/yarn/issues/2821) the only one!). You can fix it by uninstalling, adding the correct repo, and reinstalling, for example, in Debian:
- Try using [NPM](https://www.npmjs.com/get-npm) instead: So clone, cd, then run `npm install`, `npm run build` and `npm start`
- Try using [Docker](https://www.docker.com/get-started) instead, and all of the system setup and dependencies will already be taken care of. So from within the directory, just run `docker build -t lissy93/dashy .` to build, and then use docker start to run the project, e.g: `docker run -it -p 8080:80 lissy93/dashy` (see the [deploying docs](https://github.com/Lissy93/dashy/blob/master/docs/deployment.md#deploy-with-docker) for more info)
If you've got a multi-page dashboard, and are hosting the additional config files yourself, then CORS rules will apply. A CORS error will look something like:
Access to XMLHttpRequest at 'https://example.com/raw/my-config.yml' from origin 'http://dashy.local' has been blocked by CORS policy:
No 'Access-Control-Allow-Origin' header is present on the requested resource.
```
The solution is to add the appropriate headers onto the target server, to allow it to accept requests from the origin where you're running Dashy.
If it is a remote service, that you do not have admin access to, then another option is to proxy the request. Either host your own, or use a publicly accessible service, like [allorigins.win](https://allorigins.win), e.g: `https://api.allorigins.win/raw?url=https://pastebin.com/raw/4tZpaJV5`. For git-based services specifically, there's [raw.githack.com](https://raw.githack.com/)

This is likely caused by insufficient memory allocation to the container. When the container first starts up, or has to rebuild, the memory usage spikes, and if there isn't enough memory, it may terminate. This can be specified with, for example: `--memory=1024m`. For more info, see [Docker: Runtime options with Memory, CPUs, and GPUs](https://docs.docker.com/config/containers/resource_constraints/).
See also: [#380](https://github.com/Lissy93/dashy/issues/380), [#350](https://github.com/Lissy93/dashy/issues/350), [#297](https://github.com/Lissy93/dashy/issues/297), [#349](https://github.com/Lissy93/dashy/issues/349), [#510](https://github.com/Lissy93/dashy/issues/510), [#511](https://github.com/Lissy93/dashy/issues/511) and [#834](https://github.com/Lissy93/dashy/issues/834)
In Docker, this can be caused by not enough memory. When the container first starts up, or has to rebuild, the memory usage spikes, and so a larger allocation may be required. This can be specified with, for example: `--memory=1024m`. For more info, see [Docker: Runtime options with Memory, CPUs, and GPUs](https://docs.docker.com/config/containers/resource_constraints/)

In V 1.6.5 an update was made that in the future will become a breaking change. You will need to update you config to reflect this before V 2.0.0 is released. In the meantime, your previous config will continue to function normally, but you will see a validation warning. The change means that the structure of the `appConfig.auth` object is now an object, which has a `users` property.
Version 2.0.4 introduced changes to how the config is read, and the app is build. If you were previously mounting `/public` as a volume, then this will over-write the build app, preventing it from starting. The solution is to just pass in the file(s) / sub-directories that you need. For example:
Check the [browser's console output](#how-to-open-browser-console), if you've not set any headers, you will likely see a CORS error here, which would be the source of the issue.
You need to allow Dashy to make requests to Keycloak, and Keycloak to redirect to Dashy. The way you do this depends on how you're hosting these applications / which proxy you are using, and examples can be found in the [Management Docs](/docs/management.md#setting-headers).
For example, add the access control header to Keycloak, like:
`Access-Control-Allow-Origin [URL-of Dashy]`
Note that for requests that transport sensitive info like credentials, setting the accept header to a wildcard (`*`) is not allowed - see [MDN Docs](https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS#requests_with_credentials), so you will need to specify the actual URL.
You should also ensure that Keycloak is correctly configured, with a user, realm and application, and be sure that you have set a valid redirect URL in Keycloak ([screenshot](https://user-images.githubusercontent.com/1862727/148599768-db4ee4f8-72c5-402d-8f00-051d999e6267.png)).
For more details on how to set headers, see the [Example Headers](/docs/management.md#setting-headers) in the management docs, or reference the documentation for your proxy.
If you're running in Kubernetes, you will need to enable CORS ingress rules, see [docs](https://kubernetes.github.io/ingress-nginx/user-guide/nginx-configuration/annotations/#enable-cors), e.g:
If you get an error similar to the one above, you are mounting a directory to the config file's location, when a plain file is expected. Create a YAML file, (`touch my-conf.yml`), populate it with a sample config, then pass it as a volume: `-v ./my-local-conf.yml:/app/public/conf.yml`
If you're running Dashy using a static hosting provider (like Vercel), then there is no Node server, and so the save config action will not work via the UI.
You'll instead need to copy the YAML after making your changes, and paste that into your `conf.yml` directly. If you've connected Vercel to git, then these changes will take effect automatically, once you commit your changes.
If you're running on Netlify, there are some cloud functions which take care of all the server endpoints (like status checking), so these will work as expected.

Dashy has the option to save settings and config locally, in browser storage. Anything here will take precedence over whatever is in your config file, sometimes with unintended consequences. If you've updated the config file manually, and are not seeing changes reflected in the UI, then try visiting the site in Incognito mode. If that works, then the solution is just to clear local storage. This can be done from the config menu, under "Clear Local Settings".

## Config Still not Updating
Sometimes your text editor updates files [inode](https://linuxhandbook.com/inode-linux/), meaning changes will not be picked up by the Docker container. This [article](https://medium.com/@jonsbun/why-need-to-be-careful-when-mounting-single-files-into-a-docker-container-4f929340834) explains things further.
If you find that your styles and other visual assets work when visiting `ip:port` by not `dashy.domain.com`, then this is usually caused by caching. In your browser, do a hard-refresh (<kbd>Ctrl</kbd> + <kbd>F5</kbd>). If you use Cloudflare, then you can clear the cache through the management console, or set the cache level to Bypass for certain files, under the Rules tab.
This situation relates to error messages similar to one of the following, returned when pulling, updating or running the Docker container from Docker Hub.
You have reached your pull rate limit. You may increase the limit by authenticating and upgrading: https://www.docker.com/increase-rate-limit
```
When DockerHub returns one of these errors, or a `429` status, that means you've hit your rate limit. This was [introduced](https://www.docker.com/blog/scaling-docker-to-serve-millions-more-developers-network-egress/) last year, and prevents unauthenticated or free users from running docker pull more than 100 times per 6 hours.
You can [check your rate limit status](https://www.docker.com/blog/checking-your-current-docker-pull-rate-limits-and-status/) by looking for the `ratelimit-remaining` header in any DockerHub responses.
- Dashy is also available through GHCR, which at present does not have any hard limits. Just use `docker pull ghcr.io/lissy93/dashy:latest` to fetch the image
The configuration file is validated against [Dashy's Schema](https://github.com/Lissy93/dashy/blob/master/src/utils/ConfigSchema.json) using AJV.
First, check that your syntax is valid, using [YAML Validator](https://codebeautify.org/yaml-validator/) or [JSON Validator](https://codebeautify.org/jsonvalidator). If the issue persists, then take a look at the [schema](https://github.com/Lissy93/dashy/blob/master/src/utils/ConfigSchema.json), and verify that the field you are trying to add/ modify matches the required format. You can also use [this tool](https://www.jsonschemavalidator.net/s/JFUj7X9J) to validate your JSON config against the schema, or run `yarn validate-config`.
If you're trying to use a recently released feature, and are getting a warning, this is likely because you've not yet updated the the current latest version of Dashy.
If the issue still persists, you should raise an issue.
Please acknowledge the difference between errors and warnings before raising an issue about messages in the console. It's not unusual to see warnings about a new version of a certain package being available, an asset bundle bing oversized or a service worker not yet having a cache. These shouldn't have any impact on the running application, so please don't raise issues about these unless it directly relates to a bug or issue you're experiencing. Errors on the other hand should not appear in the console, and they are worth looking into further.
If you're using status checks, and despite a given service being online, the check is displaying an error, there are a couple of things you can look at:
If your service requires requests to include any authorization in the headers, then use the `statusCheckHeaders` property, as described in the [docs](/docs/status-indicators.md#setting-custom-headers).
If you are still having issues, it may be because your target application is blocking requests from Dashy's IP. This is a [CORS error](https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS), and can be fixed by setting the headers on your target app, to include:
If the URL you are checking has an unsigned certificate, or is not using HTTPS, then you may need to disable the rejection of insecure requests. This can be done by setting `statusCheckAllowInsecure` to true for a given item.
If your service is online, but responds with a status code that is not in the 2xx range, then you can use `statusCheckAcceptCodes` to set an accepted status code.
If you get an error, like `Service Unavailable: Server resulted in a fatal error`, even when it's definitely online, this is most likely caused by missing the protocol. Don't forget to include `https://` (or whatever protocol) before the URL, and ensure that if needed, you've specified the port.
Running Dashy in HOST network mode, instead of BRIDGE will allow status check access to other services in HOST mode. For more info, see [#445](https://github.com/Lissy93/dashy/discussions/445).
If you have firewall rules configured, then ensure that they don't prevent Dashy from making requests to the other services you are trying to access.
Currently, the status check needs a page to be rendered, so if this URL in your browser does not return anything, then status checks will not work. This may be modified in the future, but in the meantime, a fix would be to make your own status service, which just checks if your app responds with whatever code you'd like, and then return a 200 plus renders an arbitrary message. Then just point `statusCheckUrl` to your custom page.
For further troubleshooting, use an application like [Postman](https://postman.com) to diagnose the issue. Set the parameter to `GET`, and then make a call to: `https://[url-of-dashy]/status-check/?&url=[service-url]`. Where the service URL must have first been encoded (e.g. with `encodeURIComponent()` or [urlencoder.io](https://www.urlencoder.io/))
If you're serving Dashy though a CDN, instead of using the Node server or Docker image, then the Node endpoint that makes requests will not be available to you, and all requests will fail. A workaround for this may be implemented in the future, but in the meantime, your only option is to use the Docker or Node deployment method.
If an error occurs when fetching or rendering results, you will see a short message in the UI. If that message doesn't adequately explain the problem, then you can [open the browser console](/docs/troubleshooting.md#how-to-open-browser-console) to see more details.
Before proceeding, ensure that if the widget requires auth your API is correct, and for custom widgets, double check that the URL and protocol is correct.
If the error message in the console includes: `Error: timeout of 500ms exceeded`, then your Glances endpoint is slower to respond than expected. You can fix this by [setting timeout](https://github.com/Lissy93/dashy/blob/master/docs/widgets.md#setting-timeout) to a larger value. This is done on each widget, with the `timeout` attribute, and is specified in ms. E.g. `timeout: 5000` would only fail if no response is returned within 5 seconds.
If you're able to, you can find more information about why the request may be failing in the Dev Tools under the Network tab, and you can ensure your endpoint is correct and working using a tool like Postman.
---
## Widget CORS Errors
The most common widget issue is a CORS error. This is a browser security mechanism which prevents the client-side app (Dashy) from from accessing resources on a remote origin, without that server's explicit permission (e.g. with headers like Access-Control-Allow-Origin). See the MDN Docs for more info: [Cross-Origin Resource Sharing](https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS).
You will get a CORS error if you try and access a http service from a https source. So ensure that the URL you are requesting has the right protocol, and is correctly formatted.
If you have control over the destination (e.g. for a self-hosted service), then you can simply apply the correct headers.
Add the `Access-Control-Allow-Origin` header, with the value of either `*` to allow requests from anywhere, or more securely, the host of where Dashy is served from. For example:
You can route requests through Dashy's built-in CORS proxy. Instructions and more details can be found [here](/docs/widgets.md#proxying-requests). If you don't have control over the target origin, and you are running Dashy either through Docker, with the Node server or on Netlify, then this solution will work for you.
Just add the `useProxy: true` option to the failing widget.
For testing purposes, you can use an addon, which will disable the CORS checks. You can get the Allow-CORS extension for [Chrome](https://chrome.google.com/webstore/detail/allow-cors-access-control/lhobafahddgcelffkeicbaginigeejlf?hl=en-US) or [Firefox](https://addons.mozilla.org/en-US/firefox/addon/access-control-allow-origin/), more details [here](https://mybrowseraddon.com/access-control-allow-origin.html)
Usually this happens due to an error in your config. If you're unsure, copy and paste the [example](/docs/widgets.md#weather) config, replacing the API key with your own.
Check that `apiKey` is correctly specified, and nested within `options`. Ensure your input city is valid.
To test your API key, try making a request to `https://api.openweathermap.org/data/2.5/weather?q=London&appid=[your-api-key]`
If [Weather widget](/docs/widgets.md#weather-forecast) is working fine, but you are getting a `401` for the [Weather Forecast widget](/docs/widgets.md#weather-forecast), then this is also an OWM API key issue.
Since the forecasting API requires an upgraded plan. ULPT: You can get a free, premium API key by filling in [this form](https://home.openweathermap.org/students). It's a student plan, but there's no verification to check that you are still a student.

## Widget Displaying Inaccurate Data
If any widget is not displaying the data you expect, first confirm that your config is correct, then try manually calling the API endpoint.
If the raw API output is correct, yet the widget is rendering incorrect results, then it is likely a bug, and a ticket should be raised. You can start to debug the issue, by looking at the widget's code ([here](https://github.com/Lissy93/dashy/tree/master/src/components/Widgets)), and the browser console + networking tab.
If the API itself is returning incorrect, incomplete or inaccurate data then an issue needs to be raised **with the API provider** (not Dashy!). You can find the API provider included within the widget docs, or for a full list see the [Privacy Docs](https://github.com/Lissy93/dashy/blob/master/docs/privacy.md#widgets).
See also: [#807](https://github.com/Lissy93/dashy/issues/807) (re, domain monitor)
Usually, Font Awesome will be automatically enabled if one or more of your icons are using Font-Awesome. If this is not happening, then you can always manually enable (or disable) Font Awesome by setting: [`appConfig`](/docs/configuring.md#appconfig-optional).`enableFontAwesome` to `true`.
If you are trying to use a premium icon, then you must have a [Pro License](https://fontawesome.com/plans). You'll then need to specify your Pro plan API key under `appConfig.fontAwesomeKey`. You can find this key, by logging into your FA account, navigate to Account → [Kits](https://fontawesome.com/kits) → New Kit → Copy Kit Code. The code is a 10-digit alpha-numeric code, and is also visible within the new kit's URL, for example: `81e48ce079`.
Be sure that you're specifying the icon category and name correctly. You're icon should look be `[category] fa-[icon-name]`. The following categories are supported: `far`_(regular)_, `fas`_(solid)_, `fal`_(light)_, `fad`_(duo-tone)_ and `fab`_(brands)_. With the exception of brands, you'll usually want all your icons to be in from same category, so they look uniform.
Ensure the icon you are trying to use, is available within [FontAwesome Version 5](https://fontawesome.com/v5/search) (we've not yet upgraded to V6, as it works a little differently).
If the copy to clipboard feature (either under Config --> Export, or Item --> Copy URL) isn't functioning as expected, first check the browser console. If you see `TypeError: Cannot read properties of undefined (reading 'writeText')` then this feature is not supported by your browser.
The most common reason for this, is if you not running the app over HTTPS. Copying to the clipboard requires the app to be running in a secure origin / aka have valid HTTPS cert. You can read more about this [here](https://stackoverflow.com/a/71876238/979052).
If you're running on GitHub Codespaces, and seeing: `Error: error:0308010C:digital envelope routines::unsupported` when using Node 17+, it can be resolved by adding the `--openssl-legacy-provider` flag to your `NODE_OPTIONS` environmental variable.
You can also view any and all data that Dashy is storing, using the developer tools. Open your browser's dev tools (usually <kbd>F12</kbd>), in Chromium head to the Application tab, or in Firefox go to the Storage tab. Select Local Storage, then scroll down the the URL Dashy is running on. You should now see all data being stored, and you can select and delete any fields you wish.
You will need a GitHub account in order to raise a ticket. You can then [click here](https://github.com/Lissy93/dashy/issues/new?assignees=lissy93&labels=%F0%9F%90%9B+Bug&template=bug.yml&title=%5BBUG%5D+%3Ctitle%3E) to open a new bug report.

## Git Contributions not Displaying
If you've contributed to Dashy (or any other project), but your contributions are not showing up on your GH profile, or in Dashy's [Credits Page](https://github.com/Lissy93/dashy/blob/master/docs/credits.md), then this is likely a git config issue.
