There is currently trouble with connections to the SSL server.
If you are experiencing problems connecting try a different port.
Available ports are 443, 563 and 8080.
I'm having problems too as the same port does not always work, but after a few retries it eventually connects and seems to be ok as long as I don't disconnect
