Unable to access WebUI for Calibre-web

[npinkerton]

I have installed the calibre-web docker container from Linuxserver.io in Debian on a Beelink Mini S12.

I have calibre also installed, as well as Plex and all the Arrs. Everything works, except calibre-web. Calibre-web seems to launch just fine, as far as I can tell by looking at the output from launching docker compose, and when I run lsof, I see docker listening on the appropriate port, but I get " Unable to connect. Firefox can’t establish a connection to the server at 192.168.12.245:8083" when I try to access the WebUI from the same machine (or any other machine on the same LAN).

Other containers are reachable, so it doesn’t seem to be a routing issue, as far as I can tell.

I have not been able to get any further than this. I have been searching various forums and reddit, looking for someone having the same issue, but have come up empty handed.

I am hoping that someone might have an idea (or might notice some simple stupid thing that I have overlooked). Let me know if there is any other information that you need.

I have found my own problem.

looking at the logs, I saw a message about my timezone format. the “US/Central” is the format used on every other container in my yml file… but it seems to have prevented calibre-web from launching at all.

I changed it to “America/Chicago” and it fixed my problem.

so I went ahead and updated all the other containers, as well, in case it causes any problems.

I will leave the original post up in case someone else runs into the problem.
