Authentication failure in download clients settings for qBittorrent

[DrStrange]

Is there an existing issue for this?

• I have searched the existing open and closed issues

Current Behavior

In radarr's download client settings for qbit 5.2.0beta1, radarr says there is authentication failure on the username. So the download client settings cannot be saved.

Expected Behavior

Radarr should not display any error and it should save the download client settings for qbit.

Steps To Reproduce

Go to Settings>Download Clients.
Click Add.
Select qBittorrent.
Type in username and password.
Click Test.
Radarr displays authentication failure against username.

Environment

- OS: Windows 10 22H2 19045.6691
- Radarr: 6.1.1.10317
- qBit 5.2.0beta1
- Docker Install: No
- Using Reverse Proxy: No
- Browser: Firefox 146.0.1 
- Database: Sqlite 3.50.4

Trace Logs? Not Optional

I opened an issue in September/November on qbit's github re radarr auth failure when qbit 5.2.0 was in alpha. A qbit dev said that "auth is working fine in qbit's alpha builds so this still seems to be an issue with radarr's use of the qbit api":
latest alpha builds cause communication authentication failure in Radarr & Sonarr
I mentioned issue here:
Fixed: qBittorrent /login API success check

My testing shows that when using qbit 5.2.0alpha1 builds prior to 16th October 2025 or using qbit 5.1.4, there is no auth failure in radarr. With qbit builds since 16th October 2025, including the new beta1 build, there is auth failure in radarr.

Based on the logs, seems to be because your credentials are invalid as far qbittorrent is concerned.

Restart radarr and try again, it's possible for the bad credentials to be cached which was addressed with Sonarr/Sonarr@ae18ad6.

[DrStrange]

I uninstalled radarr using revo uninstaller, deleted any radarr folders in C:\ ran Wise Registry cleaner and rebooted. I installed radarr master, set it to run at PC startup as a shortcut, updated to radarr nightly and rebooted. Radarr still has auth error with qbit.
qbit is also set to run at PC startup as a shortcut.

I installed radarr nightly and qbit5.2.0beta1 in another Windows 10 PC, which never had any previous versions of radarr and qbit installed. Radarr also has auth error with qbit.

Sonarr fails to auth qbit - same error.

I changed port 8080 to a random number in radarr and qbit, unselected all items in qbit>WebUI>Security then restarted qbit but this had no effect.

[mynameisbogdan]

I can confirm the issue after I spent some time to build the beta in a dockerfile to be able to test.

[augustuen]

Confirmed the same issue here, but I'm also seeing the same behaviour with Sonarr 4.0.16.2946.

From some preliminar testing it looks like it could be related to us sending authentication data along with the request and qBit trying to parse the API key from that.

[DrStrange]

Thanks for confirming the issue.
I will go back to using the most recent qbit build which does not have an auth failure with radarr nightly which was this one from 15th October - qbit 5.2.0alpha1 libtorrent 2.0.11.

My usual OS is Windows 10 with latest security updates but I have since test installed radarr nightly and qbit 5.2.0beta1 in a new install of an up to date Windows 11 25H2 - still same auth failure.

Should I open an issue in sonarr's github?

[mynameisbogdan]

I can confirm the issue after I spent some time to build the beta in a dockerfile to be able to test.

It is according to https://github.com/qbittorrent/qBittorrent/blob/9d5a8270cf8fb72775c6e5e1a96925a7c1ab2773/src/webui/webapplication.cpp#L648

The basic auth seems to be implement a decade ago with Sonarr/Sonarr@0552b56 so might be safe to remove with the new versions of the API.

[mynameisbogdan]

Should I open an issue in sonarr's github?

No, I already opened a PR with a fix there.

[DrStrange]

Basic auth has been added to qbit 5.2.0beta1 here (workflow build not merged pending review) so I'm going to use that build until API key support gets added to radarr and sonarr.
I no longer have a auth failure in radarr and sonarr.
I'm closing this.
Thank you.

[mynameisbogdan]

Basic auth is still a PR, so there's no promise it's going to be merged any time soon. So I wouldn't rely on it being available with 5.2.0 stable.
