can't access antman UI when port forwarding the box

I have port 443 port forwarded  to get through my router setup. I can get to the login screen, but antman doesn't preserve the incoming ports, and so instead of localhost:12345 it just uses localhost and then everything fails. I can get to it just fine when inside my lan, its just when outside and doing the tunnel antman doens't really like it.

Is there a setting somewhere I can make so that antman will use the incoming port for its urls ?

Hello ra, I contacted my support team and this is what he says:

Since he opened port 443, if he wants to connect via https with his own certificate, see the docs here: https://docs.antsle.com/https/
Using an antsle.us subdomain is only valid on the local network as it resolves to the private IP of the antsle
