Describe the bug
I am unable to connect qBitRemote to my qBittorrent server running the new version 5.2.0. Authentication fails completely when using a valid username and password (these credentials work perfectly fine when accessing the WebUI via a standard web browser).
Additionally, the "Auth Bypass" feature also fails. Even though my device's IP (or subnet) is correctly whitelisted in the qBittorrent WebUI settings, the app throws an "HTTP 403 Forbidden – Not authenticated" error during the API check.
To Reproduce
Steps to reproduce the behavior:
Update qBittorrent to version 5.2.0.
Attempt to connect via qBitRemote using standard username and password -> Fails.
Enable "Auth Bypass" in the app and whitelist the device IP in qBittorrent settings.
Run the connection diagnostic.
See error: HTTP 403 Forbidden – Not authenticated.
Expected behavior
The app should successfully authenticate using either the credentials or the Auth Bypass feature.
Environment:
Platform: iOS 26.4.2
App Version: 2.1.1
qBittorrent Version: 5.2.0
Additional context / Diagnostic Log
Below is the diagnostic log from the Auth Bypass attempt:
