Once your SSH access has been activated for your account, there can be a short delay while the SSH account is set up on our servers and the details are updated for you to enable the access fully.
This usually only takes around an hour at the most, so if you are having trouble logging in, wait for an hour, then try again.
If your login still fails after this time, please raise a Support Ticket with the Customer Services team so they can look into it for you.
