tFTPFileList_1 error caused by: java.io.EOFException: SSL peer shut down incorrectly

[Anonymous]

All the standard troubleshooting that I could possibly think of has been done.  

• FTP application like filezilla and WinSCP have no issues connecting and moving files from the same server.
• I have tested the below config successfully with a standard open FTP.  As well as an SFTP server.  Both were off site and outside the network.
• I have obtained the target FTPS server's self signed cert and loaded it into java's cacerts.  I get the same error when using a new mykeystore.jks file.

I will not be offended if you ask me about other troubleshooting steps.  Any questions / thoughts / theories are much appreciated.

Hello,

Thanks for your suggestion.

For the warning message, it is normal actually.

These error messages are Java side and it appears like this is a known warning with Open Zulu JDK11 regarding the Reflection packages in Java. This warning is telling you that this is a feature that might be restricted (or not available) in the future. This typically will not prevent the Job from running or completing.

Best regards

Sabrina
