Thanks for checking this out!
So I am trying to make a server for me and my friends to use when we're gaming. I have port-forwarded 10011, 30033 and 9987. I downloaded the latest TS3 Server files and ran the "ts3server_win64.exe" on my other computer and connected successfully on my main computer. I used the admin authorization key successfully and edited the server to my liking. But when I close and re-open the TS3 Client it says "ERROR" when trying to connect. But I noticed that I can keep the TS3 Client open and disconnect and reconnect all I want, it only becomes a problem when I close the Client and try to connect again.

PLEASE HELP!!!
