I did upgrade yes.
I tried to check if Transmission is running via OpenVPN. Strangely, it isn’t.
I tested by adding the magnet link from this site via SSH to Transmission:
https://torguard.net/checkmytorrentipaddress.php
Weirdly, in Transmission it showed my actual IP (provided by my ISP). Perhaps I messed around a while ago when I tried this (never got that working). Don’t remember. Maybe I should do a clean install.
