Lost connection to mySQL at 'reading initital communication packet', system error: 0 (no replies)

This is my first attempt at MySQL Workbench.
I'm trying to connect from my Windows PC to my database on the server at my web hosting site (www.1and1.com).

I get the error:

"Failed to Connect mySQL at xxxxxxx:22 with user xxxxxxxxx
Lost connection to mySQL at 'reading initital communication packet', system error: 0"

________________________________________________________
These are the options I have used:
Connection Method: Standard TCP/IP
Hostname with port number: xxxx:22
Username: xxxxxx
password: xxxxxxx

I have also tried using SSH - same result

I've tried disable my AVG firewall - it made no difference

I have used the same credentials logging on through PuTTy. This worked fine.
But I want a graphical SQL interface.

Can anybody help?
