Sonarr - qBittorrent client 400 error

Help & Support
1

Hi,

Been using Sonarr for awhile now and I love it!. Decided to try my hand at using qbittorrent and got everything setup but when Sonarr attempts to validate the /version/api string qbittorrent is on version 3.3.1 and the web url returns a 7.

Based on this file: src/NzbDrone.Core/Download/Clients/qBittorrent/QBittorrent.cs

I was able to determine that Sonarr seems to only go up to 6 on line 196 which i’m persuming is the issue. since version 3.3.1 of qbittorrent has an API of 7 Sonarr isn’t quite sure what to read from the output so it generates a 400 error.

If you need more information just let me know but hopefully this gets you pointed in the right direction. I’m guessing this’ll be a simple fix.

Just bumping. in case anyone has any recommendations.

I’m having the same issue, except I’m using qBittorrent 3.4.x and the api number is now 8

Would love to test sonarr as a possible replacement for some other package that has seen a lot of drama recently xD

API version 5 is the minimum allowed version, though version 6 is recommended to support setting the category through the API.

The 400 response is a response from qBittorrent when Sonarr asks for its version number, Sonarr makes a very simple request to qBittorrent, but in some setup it fails to respond properly and instead returns a 400 response.

If you’re seeing this, please let us know:

  • Which version of Sonarr
  • Which version of qBittorrent
  • Which OS Sonarr is running on
  • Which OS qBittorrent is running on
  • Which version of mono (is Sonarr is not running on Windows)

Here is my info :slight_smile:

version of Sonarr: 2.0.0.3732
version of qBittorrent: 3.3.2
Sonarr is running on ubuntu server 14.04
qBittorrent is running on windows 7
version of mono:4.2.1 (Stable 4.2.1.102/6dd2d0d Thu Nov 12 09:52:44 UTC 2015)

Thanks for the information, this is affecting Sonarr on mono only and seems to be a bug with the library we’re using to make connections to download clients, but qBittorrent is extra strict and is failing.

Hey, I’m new here…

Just installed all of this today hoping to get it setup but I ran into this same issue

Sonarr Ver. 2.0.0.3934
qBittorrent: 3.3.3
Sonarr is running on Ubuntu Server 14.04
QBittorrent also on Ubuntu Server 14.04

I put Transmission BT Client on which seems to work but I really like qBittorrent, the ability to make changes without having to sudo nano edit_some_file.conf to change my password would be nice.

Which version of Sonarr: 2.0.0.3970 - 2016-03-17 (DEVELOP)
Which version of qBittorrent:qBittorrent 3.3.3
Which OS Sonarr is running on: Windows 10_x64
Which OS qBittorrent is running on: Windows 10_x64

On the download clients page if I use the test button, I get a success message.

This was all working before the install/upgrade today, error in log is:
