can you connect to ssh service on port 22 on that vps ?
let me guess. the answer is yes.

you can use http://portquiz.net/ to test connection to specific tcp ports. use 

Code: (Select All)

cat < /dev/tcp/portquiz.net/22

 in this case. my guess is you will see you can.

I think your iptables (firewall) is not configured to let incoming on 22.

check the rules using iptables -L

let us know.
