Nginx proxy issue

Okay. So I’ve set up nginx proxy manager on my unraid server. Port forwarded 80 -> 1880 and 443 -> 18443. Set up Jellyfin through it. When I’m not on wifi, going to the domain I set works flawlessly. Love it. 10/10.

But when I’m on my LAN, and I go to the domain, it tries to load up my OPNsense interface. Does anyone know how to solve this? I’ve been trying for hours and idk if I’m missing something obvious but I can’t figure it out.
