The problem is the Server Key is more modern than Default for Putty, So if you go to your configuration for PUTTY and change the SSH > Key to use Diffie-Hellman group 14 SSH works again. Apologies for opening ticket but I could not find any one with a resolution and no one in even putty forum suggested changing the default cipher Key. So I guess I answered my own Question
