qbittorrent broken for anyone else or just me?

sonarr and radarr can't connect. I see it was restarted 3 days ago and has a new port. I can deal with that :) Entering the new port, it sonarr now says "Received an invalid status line". same with radarr. qbittorrent web ui is fine. Logs don't indicate any problems. SSL is unchecked in both sonarr and qbit. Authentication is unchanged, but I reentered my password in the downloader settings just in case. Have restarted sonarr, qbittorrent, and the seedbox. Restarted the laptop, unplugged my network cable to blow out any dust, etc :)

I wonder if qbittorrent has been recently updated?
