Hello Experts
In my current project I have run into a scenario wherein I have to pick the files from an external FTP server (which is not on client network) via the internet proxy server.
I am using SAP PI 7.3 which provides the option for FTP proxy and I have tried using it in all permutation and combinations but still fail to get it work.
Either running into 'The FTP server returned the following error message: 'com.sap.aii.adapter.file.ftp.FTPEx: 520 Unexpected reply codeControl connection prematurely closed by server'. For details, contact your FTP server vendor' error or into
'Error occurred while connecting to the FTP server "xxx": java.net.ConnectException: Connection refused: connect' error.
Any pointers on how to configure the Sender FTP communication channel to connect an external FTP server via internet proxy would be highly appreciated.
Note: - The Firewall settings have been correctly configured and I am able to connect to the FTP server via Internet explorer but instead of ftp://ipaddress, I am accessing the FTP server via ftp://username:password@ipaddress link as the former one (ftp://ipaddress) doesn't seem to work.
Thanks
Nishad
