OSError: [Errno 98] Address already in use

There seem to be an instance running already, respectively the port is used already:

ss -tlpn

octoprint serve

Ah, you ran that manually from console? Note there is a service started, which does that already, at boot and after the software install:

systemctl status octoprint

[MateuszJuszczyk]

ss -tlpn result

octoprint status

Also I installed again and same issue.

[Joulinar]

can you reboot your system and check the system log

journalctl -u octoprint

if possible, try to avoid creating screen prints. You should be able to copy the whole output from SSH terminal directly.

Works fine here on my ROCK Pi S Bullseye system. Looks like an issue with the automatic language selection in your case. This is selected based on the browser language. Which one is it in your case, and does it work when you change it to e.g. English?

This best_match(LANGUAGES) seems to not find any match in your case, and a sanity check + fallback to English seems to be missing, to that it returns an exception instead. Might be simple to fix this at OctoPrint end.

You are completely right, thank you. It was browser issue (Brave). On chrome it loaded. Both have polish language.

Ok I'm going to close the issue for now, feel free to reopen if needed.

This has been fixed for next OctoPrint release 🙂:

• 500 response when requesting /api/currentuser caused by Babel OctoPrint/OctoPrint#4744
