Third Party Mirror wont work across servers

so I have the thing for Network Address set to my IP and when I hit "Host (Server + Client)" the Client address = localhost, this may not be a bug but it seems like it is, I've looked around for other forums that have the same question yet I can't find any. I'm new to using Mirror.

Basically:
in the Network Manager component:
Network Info
Network Address: [my ip]

in game:
Server: active. Transport: (idk if what it says here is personal info or not so I wont put it)
Client: address=localhost

any help?
