Your command (ssh -v example.cloudapp.net : 22) says to connect to example.cloudapp.net and then execute the command : 22 and exit.

From what I can see it succeeds in doing this.

I would guess that you tried to specify the port number(?) but that is not how you do it. First of all, port 22 is default for ssh, so there's no need to specify it but if you need to specify a port, use -p.

For some info on what : 22 means:

$ type :
: is a shell builtin
$ help :
:: :
    Null command.

    No effect; the command does nothing.

    Exit Status:
    Always succeeds.
