I suspect you have not configured the knownhosts file.

Please can you post atleast an error message with some more information?

Was this issue resolved?  We are having a similar issue.  We are cloud-based, APPS10, so not sure whether we need to setup the knownhosts_file or whether we can do that internally or if cloud services has to handle that for us.

Thank you.

Hi, 

We had to create the Knownhosts_file, but it was a APP10. I am not sure about Cloud service.

To create the Known hosts info.

If the known hosts file does not exists, or is in an incompatible file format, a new known hosts file can be created with the following command:

java -cp <IFS_HOME>\repository\server\javaruntime\ifs-fnd-connect.jar;<IFS_HOME>\repository\server\dist\lib\jsch-0.1.53.jar ifs.fnd.connect.ftp.SftpClient -CreateKnownHosts=KNOWNHOSTS -hostname=SFTPHOST -username=USERNAME -password=PASSWORD
