Don't forget to turn on ForwardAgent on the jump host as well. You need
to keep forwarding the agent.
It's also possible that the OS on the jump host has disabled forwarding
in the sshd for some security reason. That's AllowAgentForwarding in
And if you've copied your profile around make sure you only run an
ssh-agent if you don't already have one. It's possible you are running
another one and overwriting the environment variable. The new agent
won't have your keys.
