Dynamic-IP services and Jellyfin; Strange behaviour.

[martyc1981]

I'm using a Dynamic DNS service (No-IP) to mask the URL(IP) of my Jellyfin server. There is a strange behaviour though; Whenever I connect through my Dynamic-DNS, Jellyfin no longer allows me to go Fullscreen. I can still press F11 to hide the browser window and fake fullscreen, but the fullscreen control no longer works. If I connect via my actual IP, Jellyfin works correctly. Has anyone got a fix for this?

Note: I pay for my DDNS, so there's no adverts or anything keeping the video's from going fullscreen.

I'm assuming you are using a reverse proxy. Which one and can you share the config? (censor the domain)
