My free account runs cloudflared tunnel just fine for jellyfin. Is it just plex?

I use the tunnel because my girlfriend cant install tailscale on her work laptop, so this way she can still login to jellyfin while traveling.

Why would anyone expect anyone else to serve video for them for free? Is there any CDN that serves video for you for free???

I'm not even talking about the copyright implications here, just the bandwidth costs. A single movie download would cost more than many hundreds of typical simple HTTP website sessions.

It’s not enforced in practice unless you run a giant server with a lot of traffic.

You can use Cloudflare for DNS, but you just can’t use them for proxying the traffic. I use Cloudflare with proxying on for everything other than a plex subdomain.

Do you have IPv6 from your ISP?

I use IPv6 only Emby and Jellyfin servers with my friends. We all have native IPv6 and it works well for us.

You could just disable cdn/caching.

i use it for my jellyfin and it just works, been months like this
