The device in the picture is a ROG Ally, not a Steam Deck. Without trackpads it’s a lot less useful, in my opinion.

At least with Proton VPN, it seems that some VPN servers are blocked while others aren’t. Trying with one server worked, while another resulted in a 403 Forbidden error.

Seems like the solution is to just change VPN servers until you find one with an IP that isn’t blocked. Otherwise, the Torrentio configuration page shows the following message, and Torrentio itself can’t be used in Stremio:

If you use Torrentio with Stremio, Torrentio blocks VPNs, though I don’t know why a VPN block would be impacting one platform but not another.
