Errors, what do they mean

Lately i get more errors. I have to restart sometimes the pi too, cause the addon inside homeassistant (unifi controller) sometimes gui isnt responding

what do these errors mean?

There are a bunch of different errors there. Most of them look like your Pi doesn’t have external network access. [Connection refused] and anything that’s showing an external domain.

thats strange cause it does have external access

but the sometimes the unifi controller doenst work
dunno why

again my unifi controller gui is unreachable
Nor can home assistant read stuff from my unifi controller

then suddenly it comes back up for a few hours, then it loses connection again

what the hell is wrong?

now i see this

Have you considered there may be an issue with your Unifi controller? Maybe reach out to Unifi for support if its own GUI is unreachable
