Additional info
I think the logs contains all the interesting information. I can add more if needed. This also happens after restarting Home Assistant.
Maybe it's something around these changes?

Is it possible to install a former release of this addon to verify it's working fine?
Hi @webwurst. I just submitted a PR that allows this EDGE addon to start without issues. It seems to all be working, with both Prometheus and HA metrics showing up. Plus Grafana can see the Prometheus data, too. You can grab the files from my github or just edit the few files by hand.
Now I'll have to decide whether to use Prometheus or InfluxBD for long-term metric storage...
@42Network is there an easy way for me to test your container image? Like editing some config file with registry/container-name?
Nice to see an upgrade to Prometheus version 2.40.1 :) Just the permission errors are still persisting and prevent Prometheus to start for me.
Noting that in the review for #49, @frenck mentioned that prometheus should run as root: https://github.com/hassio-addons/addon-prometheus/pull/49#discussion_r926048521
