If you cannot sign in to the qBittorrent Web UI, these are the most common causes and fixes.
Credentials. Your Web UI username is your seedbox account username — the same one you use for the control panel and SSH. The Web UI sign-in is set at signup to match your seedbox account sign-in from your welcome email. The legacy qBittorrent factory default mentioned in some older guides no longer applies on current Pulsed Media seedboxes — try the sign-in from your welcome email first.
If you changed the Web UI sign-in from inside qBittorrent (Tools → Options → Web UI) and can't remember what you set, open a support ticket from the client area. We can reset it directly on the server — no downtime.
If the tab shows an error or fails to load, the qBittorrent process may not be running. Start it from the control panel, wait a few seconds, then reload the tab. If you have SSH access, you can also check with ps aux | grep qbittorrent-nox.
If it still fails, check recent announcements on our status page or contact support. Include the exact error message you see and roughly when it started — that lets us trace the cause quickly.
