I'm getting this error in Unity when I try to launch a game server: Code (csharp): Connection Tester reports NAT target 184.108.40.206:10735 not connected to NAT facilitator 220.127.116.11:50001. It also tells me that I have a private IP address - whereas I'm pretty sure it's always been a public address up until today. Am I right in assuming the issue lies with my ISP and that I may have to ask them to either switch me back to a public address (or more likely) upgrade me to another plan? Or could it be something to do with the Master Server. FYI - I haven't changed any of my network code.
