The Server's host key is not cached in the registry. You have no guarantee that the server is
the computer you think it is .
The server's rsa2 fingerprint is:
ssh-rsa 2048 f4:0d:f3:39:40:9c:3a:f5:36:1d:7c:71:1c:55:15:bd
if you trust this host, hit Yes to add the key to
PuTTy's cache and carry on connecting.
If you want to carry on connecting just once, without
adding the key to the cache, hit No.
if you do not trust this host, hit cancel to abandon the connection.
