Receiving nat punchthrough attempt from target failed

Unity Engine
1

Hi,

I have created my own master server. If i create a room from one network(N1), and try to join from other network(N2) which is a hotspot of mobiledata. It throws this error on both joining side and server side.

In the same case,

  1. If i tried to connect from same network (i.e) creating room on N1 and trying to join from N1. It works fine.
    2)If i tried to connect between two network (i.e) creating room on N1 and trying to join from N2(which is mobile data). It works fine. direct (External IP)

Please guide me some way to progress.

FYI: I have let the permission for allow ports on my server, where my master server is running./ Tried without firewall too.

Not sure how much that helps…

See what you can make of it.

I’ll keep digging.
