Since a few days, i encounter a popup saying “failed to fetch” in any grafana dashboard i am opening up.grafana playground web page
Is it browser specific? E.g. builtin browser ad blocking, some plugin (uorigin, …)? Any error in browser console and network tab?

I am also experiencing this error since last couple of days on self-managed Grafana installations. No updates were installed and no changes to queries made. No uOrigin is used. No lines in grafana.log regarding this error.
It just appears at some random times.
Browser console network tab, pls.
OK, in my case it was uBlock origin. After disabling it, the popup did not appear any more.

I am also seeing this in some of my dashboards all of a sudden:
So I would say any request with ERR_BLOCKED_BY_CLIENT is browser problem - very likely some add blocker/plugin/extension is blocking also Grafana resources.

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
### Is the bug inside a dashboard panel?
No
### Environment (with versions)?
Grafana: Grafana v11.0.0 (83b9528bce) (docker image)
OS: Ubuntu Server 22.04 LTS (aarch64 for rpi)
Browser: Google Chrome, Microsoft Edge, Firefox
### Grafana platform?
Docker
### Datasource(s)?
Prometheus, OpenSearch
