I am upgrading my project from 8.15.1 to 9.6.3. During the upgrade process, I updated SFTP module from V2.0 to V2.3 & v2.4. While connecting to ftp site, i am getting following error. I updated encryption module as well. Any suggestion how to solve net.schmizz.sshj.transport.TransportException: Server closed connection during identification exchange at
