Sonarr.app launches but no localhost

Help & Support

Sonarr version (exact version): 4.0.11.2680
Mono version (if Sonarr is not running on Windows):
OS: macOS 15.1.1
Debug logs: can’t access
Description of issue: Launches app but not localhost server

Instructions followed exactly from Sonarr - Dive in
App is code-signed.
App opens and shows 10 threads in Activity Monitor but 0.0 CPU. localhost:8989 gives “can’t connect to the server”. Can connect to jellyfin on localhost:8096.
If I double-click the app again I’m told “You can’t open the application Sonarr.app because it’s not responding.”

lsof -i @localhost:1024-65545 shows jellyfin ports open but no Sonarr.

Same thing is happening when I try install Lidaar, so maybe I’m blind to something?

Okay. Problem solved.
Believe it or not, I went looking for the log files, which should be stored in USER/.config, but that was a folder created (and locked) in 2020. So Sonarr was unable to write logs to .config, and I guess was hanging (I couldn’t make sense of the Activity Monitor sample).
I deleted the locked .config folder and restarted the mac. New .config folder in place. Started Sonarr.app, and everything worked.

What a bizarre thing.
Thanks me! You’re welcome!
Hope it helps someone else.
