Make sure that port forwarding is actually working - on ProtonVPN the port allocated to you can change regularly and QBittorent’s settings need to be updated accordingly. Easiest way to check is to click through your active torrents and check if any peer has the I (incoming) flag.

If you have not set up something like this, port forwarding is probably not working: https://github.com/mjmeli/qbittorrent-port-forward-gluetun-server

I would personally just run the plain script as a cronjob on the host though, to not rely on some random docker image.

Music streaming is also much cheaper to run than video, so they can offer more reasonable pricing.

I don’t know, add the sites where the content that you want can be found. I think Jackett also had links to the regular web pages if you want to look around.

Was not aware myself, thank you!

I do not use whisparr specifically, but generally for the *arrs you can use jackett to support way more sites. It essentially converts site specific data formats to well known formats that the *arrs support.

Except using software without updates nowadays is a very bad idea because of the Internet and security being a real concern.

It was built on yearly releases of software instead, also known as yearly subscriptions.

Not quite - you get a perpetual license for the version that was released a year before you cancelled your subscription. And for most languages this is not really practical anyway, as they get relatively frequent updates that require IDE updates, so you will just stay subscribed.

This was a fairly low business risk, high PR value move by JetBrains.
