FTPEx: 550 Unexpected reply code An unknown error occurred while processing the certificate

We have a File To FTPS Interface. Recently we upgraded from PO 7.4 to PO 7.5 .

After the upgrade the FTPS channel started throwing error :

Attempt to process file failed with com.sap.aii.adapter.file.ftp.FTPEx: 550 Unexpected reply codeAn unknown error occurred while processing the certificate

MP: exception caught with cause com.sap.engine.interfaces.messaging.api.exception.MessagingException: com.sap.aii.adapter.file.ftp.FTPEx: 550 Unexpected reply codeAn unknown error occurred while processing the certificate

This was working before on PO 7.4 version. Certs are in place and the validity check performed . We also checked if certs are properly setup for FTP. I have tried to google on this error but found nothing on " An error occurred while processing the certificate ".

Here is the connection setting of the channel:

Please guide me on what should I check or any other configuration changes I have to do in SAP PO 7.5.

It clearly shows this issues was caused due to the Upgrade to PO7.5 ,because I saw this interface working before the upgrade and the error started immediately after the upgrade.

    Hello,

    Use the XPI Inspector to troubleshoot this further. The blogs below provide examples on using the XPI tool.
