This kind of stuff happens when the server is overloaded. Don't worry about it and just connect later.

The devs are working on it.
Well,
there were no indication of server overload yet...
The server is quite stable (in terms of traffic) and it's a long way to go until it gets overloaded ...
However, there may be two reasons for that:
a) Sometimes the server is manually restarted, when small changes are made into the game server software (but that shouldn't be happening for more than a couple of minutes per day.
b) some other plaeyrs having similar problem got it resolved by contacting their network administrators or ISP's, because some admins or ISP's or firewalls sometimes block certain IP's and ports.
Please, try to contact your system admin and ask if he did any changes to the internet connection properties lately.
