Man, first the Problem with the password, which i got fixed through downgrading back to 4.6.0-1-01. Changed to my own authentication, updated and now Sonarr and Radarr say they got no authority through neither the new nor the old authentication. Even deleted the client settings in sonarr and set it up new, didn'Ät workt either. Downgrading back and Sonarr and Radarr works just fine with the new Authentication. Anyone1 who had the same problem and knows how to get the newest Qbit Version running with Sonarr/Radarr?
