Headphones Help



Hi Everyone
Im looking for some help regarding headphones setup.
Ive managed to do Sonarr and Radarr all on my lonesome, but headphones has me stumped!
Im a member of RED and Waffles, and want to add them as indexers, but every time i try add i get an error. 2FA is off and login details are correct.
Also adding deluge as a download client is not working.
In fact any setting applied gives an error.
Can someone point me in the right direction?
