Radarr: [Bug] qBittorrent 404 Error (Changed In 4.1+ Removed in 4.2)

[zero77]

When trying to test the connection or send torrents to qBittorrent it doesn't work and instead gets a 404 error.
I think this maybe because qBittorrent nightly has dropped support for their old API.

Also, i am using the most up to date nightly vershon of Radarr.

HTTP request failed: [404:NotFound] [POST] at [http://163.172.39.74:9000/login]

Looks like the API path might need to be updated here:
src/NzbDrone.Core/Download/Clients/QBittorrent/QBittorrentProxy.cs

@teejo75
Do you mean change this from "/version/api" to "/version/api/v2/"

https://github.com/Radarr/Radarr/blob/develop/src/NzbDrone.Core/Download/Clients/QBittorrent/QBittorrentProxy.cs#L47

Also, change this from "/login" to "/api/v2/auth/login"

https://github.com/Radarr/Radarr/blob/develop/src/NzbDrone.Core/Download/Clients/QBittorrent/QBittorrentProxy.cs#L267

Looks like ALL calls will need to be prefixed with /api/v2:

From https://github.com/qbittorrent/qBittorrent/wiki/Web-API-Documentation#general-information

All API methods are under /api/v2/APIName/methodName, where APIName is a certain subgroup of API methods whose functionality is related.

Also looks like the version call is now: /api/v2/app/version
There is also: /api/v2/app/webapiVersion

It's all in the documentation link.

Thanks, i have had a look through the documentation and submitted a PR:
https://github.com/Radarr/Radarr/pull/3328

I don't think those calls in your PR are correct. Not all of those commands are under the /app endpoint. I also don't think changing the version call to using webapiVersion will work as expected.

I'm not sure just changing the calls is the right way to go about it. We need to be cognisant of when the V2 API came in to effect. Changing the calls to the new API calls will break for people using older versions of qbittorrent.

Ok, I will have another look through the document.

I also don't think changing the version call to using webapiVersion will work as expected.

I will change it then.

Unless i am mistaken, qBittorrent has supported API v2 for a while but, the next stable update will be dropping the older APIs and moving to v2 completely.

Moved PR To #3356

Initial testing against V2 of the qBittorrent API appears to be successful (Adding, removing, reading torrent list etc). Probably needs fully testing to ensure priority changes, category association etc all work as well. Finally, it was tested against v4.1.5 of qBit and needs running against v4.2.0.

This issue is still problematic. The current version of Radarr does not work with development builds of QBT since the legacy API was dropped in https://github.com/qbittorrent/qBittorrent/pull/10145 on January 12th.

Its still broken. If it could be fixed ( https://github.com/Radarr/Radarr/pull/3356 ), that would be awesome because Radarr cant be used by anybody running qbittorrent from master source since January.
