Hi Jens, Thanks for reporting this problem, can you open a Jira issue?
https://issues.apache.org/jira/browse/NIFI If you can provide a full stack trace, that would be helpful. It would also be helpful to know what strategy you are using for authentication: are you using a private key or a password? Setting the log level to DEBUG for the net.schmizz.sshj logger should also provide additional details. Regards, David Handermann On Wed, May 4, 2022 at 2:46 AM Jens M.
