This works fine for me. It allowed me to connect to your server.
hook.Add( "PlayerSay", "TTN Chat Commands", function(ply, text)
if (string.lower(text) == "!newserver" ) then --Did the player say the specific command?
ply:SendLua("LocalPlayer():ConCommand('connect 198.50.26.34:27306')")
return "" --Keeps chat box from printing command
end
end)
