unable to SSH to Cluster mgmt - ONTAP 9

Hello,

I have setup a 2 node cluster across 2 VM's - I attempt to SSH into the mgmt interface via PuTTY and I receive "Error: Connection Refused" - I am able to ping the address assigned to mgmt interface. I am using the admin account and as far as I Know the access rights for SSH are enabled by default? is there somthing else I must to do in order to SSH to this?

any help/advice is appreciated.

Thanks
