Jellyseerr suddenly cannot connect to Sonarr

[ErikHallmark]

I've been using Jellyseerr without issue for well over a year, but at some point in the last two weeks a strange issue has popped up. For some reason my Jellyseerr container cannot connect to my Sonnar container. I am having no other issues with anything else on my media server, Radarr is working just fine, and sonarr is functioning normally. For some reason when Jellyseerr tries to connect to sonarr it just hangs for a few seconds and fails.

I have openned a shell in my jellyseerr container and it cannot wget/curl from my sonnar container, but it can with every other container on my server. No other container has this issue, all containers on the server are on the same bridge network. I have tried re-configuring jellyseerr to use the Docker IP, docker container name, the host IP, and the sonar domain name I have configured, none of them work.

When in the jellyseerr container shell, the "sonar" hostname resolves to the correct IP address in the docker network, but no traffic flows between the two containers.

Specs:

Hardware: 4gb Raspberry pi 4B
Software:
OS: Debian 12 (Bookworm)
docker v 20.10.24
Jellyseerr v 2.5.2
Sonarr Version 4.0.14.2939
Sonarr Package Version 4.0.14.2939-ls283 by linuxserver.io

If possible please hop onto discord so we can troubleshoot why and I can provide support easily (as discord is where we carry out support)

Did you ever find a solution to this? I appear to currently be having the same issue

[ErikHallmark]

@Licidil I never found a solution, but after a week it solved itself, I'm assuming some combination of updates/reboots/magic fixed it for me. I got quite a bit of assistance in the discord, it might be worth posting an issue there.
