Sonarr losing connection and crashing

Help & Support
1

Sonarr version (exact version): 4.0.9.2244
Mono version (if Sonarr is not running on Windows): N/A
OS: MacOS Sonoma 14.6.1
Debug logs:
Description of issue:

I keep getting the “Sonarr has lost its connection to the backend and will need to be reloaded to restore functionality. etc” error.

The Reload button doesn’t do anything. The only way I’ve found to regain access to the Web UI is to force quite Sonarr in Activity Monitor, relaunch the application, and then it’s accessible again (for a brief while) via http://127.0.0.1:8989/

Sonarr is running on a headless machine alongside prowlarr, radarr, bazaar, qbit and plex, none of which are having this issue.

Generally, on relaunch, Sonarr might run seemingly as intended for maybe a day or so, then dies again.

Any ideas on what might be causing this, or what to try to help troubleshoot this?

Thank you

Going to need logs as was requested in the post template. Should give some insight into why it is failing.

Here’s the log

Only seems to be about 3 minutes worth of logs during an RSS sync from the looks of it, so nothing pertinent to the issue in question unfortunately. Have to try and dig through all the log files to find the one that mentions the error.

Hm. That was the final log before it crashed (again). Shouldn’t this be the one with the error on it?
