Unity Networking - How to determine if NetworkServer is not listening on port.

I know this issue can sometimes crop up especially when testing on the same network:

Cannot open socket on ip {*} and port {47775}; check please your network, most probably port has been already occupied

But when you run the function it ALWAYS returns true. I basically want to make an error message on screen if this error happens but I can't determine a way of doing it.

Any suggestions?

Thanks,

 

I forgot to mention the fundtion I'm talking about:

Code (CSharp):

1. NetworkServer.Listen(47775)

 

Have you tested this on other ports, especially on ports you are very certain it is closed? If yes, and you see closed ports as open, you might as well submit a bug report about it.

 

Yes absolutely. I get the warning! The problem I suspect though is that it has still completed the function and set it the architecture it needed for the network game itself, it just can't listen. I'll submit a bug report and see if there's any suggestions.
