## Widget Errors
#### Find Error Message
If an error occurs when fetching or rendering results, you will see a short message in the UI. If that message doesn't addequatley explain the problem, then you can [open the browser console](/docs/troubleshooting.md#how-to-open-browser-console) to see more details.
#### Check Config
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.
#### Timeout Error
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.
#### CORS error
If the console message mentions to corss-origin blocking, then this is a CORS error, see: [Fixing Widget CORS Errors](#widget-cors-errors)
#### More Info
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.
