Investigating
We've received several reports from customers experiencing 401 errors for Prometheus-backed dashboards. Engineering is engaged and actively investigating the issue.
This issue happens very rarely. When the issue occurs, it causes all Prometheus queries to fail until the instance is restarted.
We have determined two possible mitigation paths. Individuals can force a restart of their instance by adding or removing a plugin. If this is not an option, please submit a Support Ticket to have your affected instance restarted.
