Im not completely sure if you’re setup but I will add that for the docker container you should take a look at qbinhex qbittorent which contains qbittorent, vpn, and a kill switch. I have used this since my migration to https://hub.docker.com/r/binhex/arch-qbittorrentvpn/
It does. I have it running on my machine, just add demix as the indexer and download client
