          [JENKINS-51318] Jenkins master fails to init a session to Windows 10 with OpenSSH

          Please see the comments in JENKINS-42856 and follow the instructions to configure OpenSSH

          Test that you can run commands without tty by executing a command like this one

          ssh USERNAME@AGENT_HOST /bin/bash -c ls
          

          Also, take a look at How to report an issue we use to know the Jenkins and plugins versions, in this case also the OpenSSH version and the Agent configuration.
