Please note this problem is after the master server crashed so that isnt the cause.
Bassicaly whats happening is when I run server it doesn't show up on the master server list.
In the past the server was running fine so I have no idea.
i know whts the propblem just you port forward on your past server i mean the port is forwarded to your first server . now you have to do open your first server and then see the internet list it will be there then close that server and open your second server and click on the first server which is showing in internet list then the name of the server will change and then reopen the internet list then it will be there :)
try disable your firewall.
thanks guys, I ended up toggling about 3 different settings
my router was wierd about it
