I’ve been using their 1€/month vps for a couple of years now as a reverse proxy, but I use HAproxy and wireguard. It’s been working flawlessly.

If you’re using torrents, I’d say your best bet would be to try to get into a Spanish private tracker and redownload everything. The ones I’m in have absolutely everything in 4k with dual audio, one being Spanish and the other being the original audio (generally English). I’m aware it might take a while to get into a good one, but once you’re in, you’ll have everything you need.

Proxmox has an official guide on how to do this, which inlcudes these examples.

There’s also a video from Jim’s Garage where he sets up GPU passthrough in an unprivileged LXC container within proxmox.

See if any of that helps.
