What’s your go too (secure) method for casting over the internet with a Jellyfin server.
I’m wondering what to use and I’m pretty beginner at this
I don't disagree, and I am one of the VPN advocates you mention. Generally there is no issue with exposing jellyfin via proxy to the internet.
The original question seemed to imply an over-secure solution so a lot of over-secure solutions exist. There is good cause to operate services, like jellyfin, via some permanent VPN.
