were you able to resolve the loading animation issue? I just set up reverse proxy for nextcloud, radarr and sonarr and both radarr and sonarr have the same issue i.e. when I try to access the sub-domain, it asks for my username/password. Once I enter that, it takes me to a page with a loading animation near the top and a message towards the bottom that just says Radarr Ver. and Sonarr Ver.
