SSH log in for sagemath cloud project

I am trying log in to one of my projects at sagemath cloud using SSH (I am using OS X 10.10.1) after adding the local copy of the public key (~/.ssh/id_rsa.pub) to the authorized_keys file in the .ssh subdirectory of the project on the remote host, which is 162.222.176.40:

$ ssh <project id>@162.222.176.40
The authenticity of host '162.222.176.40 (162.222.176.40)' can't be established.
RSA key fingerprint is 3a:40:8e:77:88:7e:f8:68:0c:28:4a:32:f8:4a:4a:25.
Are you sure you want to continue connecting (yes/no)? yes

Is this as expected? I did check ~/.ssh/known_hosts and this host does not appear. I am guessing it will be added once I log in for the first time.

It's normal to see a message like that once upon first connecting to a server. If it asks if it's ok to continue connecting, just say "yes". That public key will then be added to your local ~/.ssh/known_hosts file (associated with that IP address or domain).

There's only a problem if you see this message every time you connect to a server. In that case, the problem might be that the given key is already in your local computer's ~/.ssh/known_hosts file, but is associated there with a different IP address or domain. Try removing that line of the file, or just clearing that file completely.
