Thanks for your answer!
if I don’t fall in mistake, Jellyfin needs a VPN to be set up. I will give it a try if I cannot solve the issue in different way (I’ve never set up a VPN before and I think is not very simple…).
Plex is asking me to pay for the client on my mobile phone to watch video in remote, so it seems it is not freemium. Am I doing something wrong?
