Well, i connect to the server and does not disconnect me or give me this message, i am in about 20 minutes and all are OK.

Do you have any antivirus or firewall enabled?

if yes then please disable them and try again to see if the problem is from any antivirus or firewall software.

Do you have any scripts/dlls/coms in use?

if yes then please use /remote off and try again to connect to the server and check if the problem is from any remote/addon/dll/com.

- Thanks!
