DNS-hole widget not working

Environment

Version

0.15.2

Describe the problem

I have an app with pi-hole integration on my dashboard. It's showing the green bubble. But the DNS-hole widgets are not working.

Both, homarr and pi-hole, are running as docker containers. homarr is in a custom docker network and pi-hole is in the docker hosts network.
They cannot communicate directly. Communication is established by a reverse proxy residing in both networks.
As far as I can tell, communication is working, since the app on the dashboard is showing the green bubble. But as you see in my screenshots, both dns-hole widgets don't work.

Unfortunately, I don't even know how to start debugging this as the homarr log does not show anything related.

I don't know if you're still facing this issue OP, but it happened to me for some time. Turns out the API key that I got from Pihole was constantly changing because I didn't set a password for my pihole container using the WEBPASSWORD environment variable. So the password and API key were randomly generated every time the container was restarted, With a fixed password this doesn't happen.
