Sonarr version: 2.0.0.4753
Mono version: Stable 5.0.1.1
OS: Ubuntu 16.04 LTS via Proxmox Container
((Debug logs)): Nothing particularly useful that I could find in the logs, even with trace logging enabled: https://pastebin.com/vaBE102X
Without changing any other configuration, overnight, sonarr has decided to longer accept my form authentication username/password. Even when I manually open the config.xml to authentication:none, clear my browser cookies and restart the sonarr service, sonarr STILL directs me to a form login page that my username/password do not work on.
I have to shutdown the entire Linux container and reboot it. Only then will sonarr recognize the authentication:none parameter in the config.xml file. Once I can get back in to sonarr, I tried resetting the username/password and accessing it from different browsers, clearing browser caches/cookies, the whole nine yards… still the same issue.
I had a similar issue a year ago when I was running sonarr on Windows, but that turned out to be a simple browser issue. I’ve tested this with multiple browsers and already reset the username/password when i logged in without authentication. Still no dice.
I’m at a complete loss how something like this could happen literally overnight.
