its not tcp.port bro, it is like this
var flashvars = {
"client.allow.cross.domain" : "0",
"client.notify.cross.domain" : "1",
"connection.info.host" : "{server_ip}",
"connection.info.port" : "30000",
"site.url" : "{url}/"...
Go to Bcstorm>Bin>Debug>Settings>Configuration, Check the tcp.port ,
then
go to htdocs>app>tpl>skins>WHAT SKIN YOU USED>client.php , The tcp.port must be the same with client's port.
