I followed all the steps marked on the little info and I can not add my server



Server info --> ts.blacksmilegroup.com
join port : 9987
query port : default

I just tried to telnet to your server and it appears that telnet is not setup properly. Per the original instructions, you'll be able to find a basic guide to telnet the server. Upon entering the connection string, you should not be brought to "Press any key to continue..." then exit like is done for your server.

As I have not experienced this error, I am not sure if it is a misconfiguration on TeamSpeak or the actual server itself. However, if you do figure it out, I'd be interested in knowing what was up.
