New Jellyfin Server/Web release: 10.10.7

[I-G-1-1]

What if the host of the reverse proxy is the same machine as the Server? What do I put in the reverse proxy section (trusted proxies)? 192.168.0.34? Or do I also specify the port? I can see from here that I should not put the domain of the reverse proxy, i.e jellyfindomainname.com

So what do I do?

I think you should put 127.0.0.1 (loopback interface)
