The issue is related to recent update of EasyPrivacy

> \### What happened?
> 
> It appears a recent ublock origin update has added \`/fronten…d-metrics^\` to its block list which i've tracked down to the \`easyprivacy\` list. I understand this is in no way related to grafana, however, i cannot find any documentation nor information about what \`/api/frontend-metrics\` is, what its used for, why it exists and why i should allow it.
> 
> Grafana is showing an error pop up on every page despite grafana working perfectly without any issues. This error is misleading and ideally i would like to disable it.

> 
> \### What did you expect to happen?
> 
> For grafana to not display errors when there is nothing wrong with grafana's functionality
> 
> \### Did this work before?
> 
> N/A
> 
> \### How do we reproduce it?
> 
> 1. Use a chromium browser (e.g. Google Chrome, Edge) or firefox
> 2. Install uBlock origin
> 3. Navigate to any page and observe that grafana places a fetch to \`/api/frontend-metrics\` and displays the error (which is the problem) in the UI
