Sonarr version (exact version): 18.104.22.1682
Mono version (if Sonarr is not running on Windows):
OS: Windows 10
Description of issue: I have been trying to upgrade Sonarr V2 to V3 as V2 is now not supported by the NZB mobile app. I followed the instructions on the Sonarr site and the install works fine. When I launch Sonarr I cannot log in. I am 100% I am using the right user and passwords as I had to uninstall and go back to Sonarr V2 which worked fine.
I have manually replaced the back up files as I thought maybe this would be the cause but this has not given me any luck. I did do a back up right before upgrading also.
Any ideas what is going wrong?
