Cannot access frontend, upnp error in logs

Configuration
1

I’m running HA supervised in docker and everything has worked fine so far. Yesterday I set up an OpenTTD server in docker as well and now I can’t seem to reach the frontend. It’s reachable locally on the NUC I’m hosting it on but not other computers on the same LAN neither through my duckdns URL. Gives me an ERR_FAILED.
This is the only weird thing I can find in my logs:

Any idea what this is about?

I’m having exactly the same problem, removing discovery: and adding a upnp entry but I still get the same error and no GUI.

Did you ever solve this? Just had exactly the same thing happen. Everything was running fine for ages, I haven’t updated or added anything and now suddenly my UI is not working and I’m getting the same error in the logs.

I’m running home assistant os 5.10 and home assistant core 2021.1.5 on a raspberry pi.
