Exploring the Issue

What Causes Error 404?

The Error 404 in Grafana usually indicates that the dashboard ID specified in the URL is incorrect or the dashboard has been removed from the Grafana instance. This can happen if the dashboard was deleted, renamed, or if there was a typo in the URL.

Check for Deletion

If the dashboard does not appear in the search results, it may have been deleted. Check with your team or the administrator to confirm if the dashboard was removed. If it was deleted, you might need to restore it from a backup if available.

Review URL for Typos

Ensure there are no typos in the URL. A simple mistake in the dashboard ID or path can lead to a 404 error. Double-check the URL for accuracy.
