Find out which node ran job 49. Then try to ssh from this node to the 
server. To debug this I guess that you should make sure with "ssh-key 
-l" that you do not use your own public/private key pair and remove it 
if you have one, for the duration of the test. You should test this with 
ssh option -a to disable forwarding of the authentication agent 
connection. Also add -v to see what ssh tries to do.

Hope this helps,
