The environment maybe, enable debug output on the job and redirect
or make sure the output is logged or picked up and mailed to you.

More than likely the ssh config that used to work no longer does.
For example you had a custom section for a host in ~/.ssh/config
that is no longer valid or that file is not even being read etc...
