Grafana not working

Hi community! How are you doing?

i use Anthias for displaying PRTG dashboards and this is working fine.
I also want to use it for displaying Grafana Dashboards but had no luck with it.

When entering the URL the Asset Check fails.
When using “disable asset check” Anthias just displays: “If you’re seeing this Grafana failed to load its application files”

I checked it with chrome on my local machine and the dashboard is working fine.
I used the “latest” version Anthias and started a Docker container with the latest grafana oss version.

What can i do? I think i am doing something wrong because grafana and antias seems to me to be a standard thing to display.
