When setting up the remote connection with a RA.FTP job fails, you may need to troubleshoot the connection. This KB explain who you can troubleshoot SSL,TLS,SSH,FTP and SFTP connections from within the agent.
How can a connection of the RA.FTP agent be troubleshot?
The SSH/FTP/SFTP connection can be troubleshot outside the agent with the option -vvv, for instance:
sftp -vvv hostname
From within the agent the same can be done by setting the Java startup variable '-Djavax.net.debug=all', for instance:
java -Djavax.net.debug=all -Xrs -Xmx1024M -jar ucxjcitx.jar
