Alright, pretty sure this is the right place to post this.
I have decided to fool around with CO PServers as all I have ever coded and messed with is Java. I have touched a little bit into C# before but nothing major. But this is besides the point, actually I am fairly certain this has nothing to do with the coding of the server (oddly enough?).
Basically I have the ports 9958/5816 forwarded, added exceptions in firewall (inbound and outbound) and even tried cutting off the firewall, yet I still receive this error:
I have also used canyouseeme.org to test out if the ports are being used or are visible and that also has failed. I am doing all of this on a Windows 2008 host that is purely dedicated to this server (no other programs using any ports except mysql of course).
I have tried a lot of things so I decided it may be best to post here and see what kind of input I can get, if you need any of the codes or any other information just post below and I will be sure to give it to you.
Thanks for the help in advance!
Edit: Also forgot to mention (although its provided in screenshot), this is a 5165 source. Also I have now tried disabling IPv6 (suggestion from a friend), and still gives same error.
