Maybe you are copying the incorrect link? All of them work for me. Make sure you are copying the link to the plugin code and not the torrent website itself.

Here is the official tutorial: https://github.com/qbittorrent/search-plugins/wiki/Install-search-plugins#steps-to-install-search-plugins-qbittorrent-version-3110-or-more-recent

In qBitorrent go to Search Plugins in the bottom right, then Install a New One. You’ll go to that website link I posted and find a torrent site that has lots of content you like, like 1337, and click the little download icon off to the right of it in that table. That will open a tab with some computer code looking stuff. Copy this URL of the website and in qBittorent, in the Install a New One window, select web link and paste the link to the search engine plugin you chose. I did this for the top 10 or so most relevant looking websites for me in terms of language, content type, etc.

Now when I need a torrent I just go to my search plugin section of the program and type in the search terms I would normally use on Rarbg, and I find the movie I’m looking for.

Here is a YouTube video I found talking about the process:

Rarbg going away was what finally got me to learn how to use qBittorent’s built in search engine which has solved my issues and made it effortless to find torrents without going to sketchy websites.

Go to the search section and add custom search engines and fill in all the good sites from this list:

Ah, good point.

Correct, I also read that the .ml addresses were free, but in hindsight this downtime is a bigger cost to bear than the $10/year or whatever it would cost to properly pay for a domain.
