Error in backend container
I'm trying to run SurfSense in containers via podman. The quadlets and env-files can be found at: https://github.com/woutercoppens/Bluefin_Linux/tree/main/quadlets
The backend gives an error: [Errno -2] Name or service not known and restarts the container:

How can I put the container in debug mode to see what is going on?
I’d like to take on this issue. The error suggests a DNS/name resolution problem inside the container. I’ll debug by running the container in interactive/verbose mode, checking env vars, network settings, and logs. With experience in Podman, systemd quadlets, and backend debugging, I’m confident I can quickly identify and fix the root cause.
You can find my quadlets here: https://github.com/woutercoppens/Bluefin_Linux/tree/main/quadlets
Hi, I'm getting the exact sam error. Has the solution already been identified?
Kind regards, Erwin
