I have two servers that I have been able to connect fine as s1.website.com and s2.website.com
I connected to s1.website.com earlier today without any issues, however, when I connected to s2.website.com it gave me the "Server Unexpectedly Closed Network Connection"
I have researched this elsewhere and someone concluded it to a "brute force attempt" However, I know this is not the case.
If anyone else has had this issue please let me know. Thanks
