I was having trouble accessing my WebUI also and claude opus 4.6 walked me through a fix fairly painlessly. I use PIA for my VPN. Here is the AIs summary FYI If your binhex-qbittorrentvpn WebUI suddenly stopped loading with PIA: Check your supervisord.log for the line: PIA endpoint '...' is NOT in the list of endpoints that support port forwarding PIA has been quietly removing port forwarding support from certain endpoints (e.g., japan.privacy.network). If you have STRICT_PORT_FORWARD=yes, qBittorrent will silently fail to start. Fix: edit the remote line in your .ovpn file to a supported endpoint from the list in your log. Stick with .privacy.network domains — the .pvt.site ones may not work with OpenVPN configs. Restart your arr containers after so they reconnect cleanly. If you need help parsing your logs, claude.ai is surprisingly good at it.
