It might be easier for you to torrent normally while connected to VPN, then disconnecting to stream to your device.

I can’t offer help on the issue, but as far as I understand there are no legitimate and safe versions of popcorn time anymore. The main version got taken down a few years ago iirc. There’s still plenty of unsafe versions though. Might want to double check you got it from a safe source.

What software did you use you monitor this? I am newish to self hosting and would like to secure my connection better.

Didn’t that have something to do with shadow bans on Reddit?
