Hi,
After I change my public IP to my real public IP I got the following errors, and I don't know the reason. I try use a administration to run Unity.
Here is the errors:
1.Connect() failed: System.Security.SecurityException: Unable to connect, as no valid crossdomain policy was found
at System.Net.Sockets.Socket.Connect_internal (IntPtr sock, System.Net.SocketAddress sa, System.Int32& error, Boolean requireSocketPolicyFile) [0x00000] in <filename unknown>:0

Thank you so much.

the port 843 is not forwarded to the machine so the policy server isn't reachable
