Hi, All:

we have 'Reflection for secure it server for windows' installed on windows 2012 server. it works as sftp server and client.

any idea regarding how to trouble shooting or find more log from the tool it self will be great.  above log is getting from batch files by using -vvv.

thanks in advance
