Sonarr version (4.0.16.2944:
Mono version (if Sonarr is not running on Windows):
*Window 11:
Debug logs:
This issue is similar to the topic : “Cannot add new show or download anything” Feb 19
however it is closed. Sonarr is not updating files, nor am I able to select download files.
Recently, I had to download Sonarr, Radarr and Sabnzbd to a new computer. Restored config files with backups. After a day or two I had the issue with Sonarr, however Radarr works fine. Uninstalled and reinstalled Sonarr replaced config files with backups. That worked for a couple of days. Issue returned and no problem with Radarr. It there a possibility the issue could be a permission issue with the C:\Data\Media\TV file?
Log level was already set a debug.
I’m not clear if I can copy and the paste the Log file. Here it is:
