I don't believe the problem is related to the Stalker middleware software or the way you have it configured although it is possible, I believe it has to do with the servers and I believe they are working on them although they may be overloaded with too much demand or there may be a problem with the internet service they are connected to. Either way, if the servers are offline, being worked on or simply not available, you will get no connection notice which comes after the Stalker middleware makes its attempt to connect to the server based on the configuration you have configured it with.
