Please provide the following information

qBittorrent version and Operating System

4.2.5 & Windows 10

What is the problem

Cant add a torrent file

What is the expected behavior

Add the torrent file

Steps to reproduce

Create a torrent (same torrent) for multiple trackers & try to add them

Extra info(if any)

So i upload to a handful of sites and the process is automated on my end. I click a file and click go and it runs.

Creates .torrent
Uploads to the tracker
Downloads their copy of the .torrent
Adds to qbt

So if i upload to multiple trackers, there will naturally be the same file multiple times however the trackers are different. Each site has different rules for the amount of time to seed it so merging all the trackers into a single file is not an option. How about some modification to the "duplicate" logic to actually allow it to be added since it is not a duplicate in terms of a different tracker.

Actual error: {NAME} is already in the transfer list. Trackers haven't been merged because it is a private torrent.

It's not possible because the info hashes are same for all those torrents.

It should actually be fixed by the tracker operators.
It literally takes 3-5 lines of codes to add an entropy to the info dict in their torrent uploader script so the info hashes are unique when redownloaded.
But alas they choose not to do it!

@austinwbest

Two torrents are the same if their info dicts are equal. If you want to make to otherwise equal torrents different, you need to embed a "source" string/tag in the torrent. if the trackers you upload to don't automatically give you an edited copy of the torrent with a "unique" "source" tag upon uploading, you need to do it yourself from the get-go, when creating the torrent.

In qBittorrent's torrent creator, this is done by filling in the Source: field at the bottom.
In mktorrent, this is done with the -s (or --source) flag. Requires mktorrent version 1.1 or above.

Some trackers have rules specifying what exact source string you should use. Typically they are short, such as BTN or PTP.
