Hello Ranjana S G,

Welcome to the MS Q&A platform.

The error message suggests the FTP server has timed out because the server was not reachable.

Please check the FTP server configuration and see if you increase the timeout.

You can also try to check the network connection between the FTP server and the Azure Data Factory and make sure that the connection is stable and there is no interruption.

And if you are transferring a large file, please try splitting the large file into small files and try the transfer again to see if it success.

I hope this helps. Please let me know if you have any further questions.
