Cannot Access Server from Home Network, but Cellular Works

What kind of router do you have?

Can you share screenshots of Dashboard > Networking?

Hey sorry for the delay, and also for the duplicate thread! Thought I deleted this one haha. But anyway thank you so much for your help thus far! 

Tried finding loopback settings for the router, no luck with that. My router is one I was given from Spectrum (so that may part of the issue. probably should just go buy my own) with a model # of SAC2V2S. It has the lovely feature of only being able to edit its' settings from a phone app... Yet another reason I should go buy a different one lol. 

And I'll include screenshots of my Jellyfin network page to this reply also. 

I saw a few threads talking about creating a separate domain to login to from when I'm on my LAN, what are your thoughts on that? Or is the best course of action to go get a router which supports loopback, if mine indeed cannot do that?

Again, I appreciate all your help!
