Hi Team, I have a question regarding open ssh issue. We have a SFTP automate process to upload file at customer server using ssh key based authentication. But some simultaneously process going in hung state. I have enable verbose mode but I am not able to understand that log. Can you please let us know by below log why we are facing this issue?
