java.io.IOException: FtpIOException --> Return Value: 425 Description: Unable to set up passive list

[sieusaopolo15]

Many of mine data sources are failing due to this error "java.io.IOException: FtpIOException --> Return Value: 425 Description: Unable to set up passive listening socket.". I tried to find posts or support posts to find if there is any similar error like mine but there is none. May I ask what is this error and how does it happen ? Does this error belong to FTP Server not my ServiceNow instance ?

At the end of the message, there is an detail but I don't sure what is it ?

At the end of the error there is an detail like this 

"211 End (for details use "HELP command" where command is the command of interest)
215 UNIX Type: L8
200 Type set to I.
425 Unable to set up passive listening socket."

Hi @Maik Skoddow, Those information I shared on the post are the detail of the Import log from data source. In the post, I did share what connection type my data source is using. And what I want to ask from this post is the main error is coming from my instance or coming from FTP Server because it is unable to set up the socket and FTP server is not from my side to manage, it is managed from the third-party team.

Hi @sieusaopolo15 

thanks for the additional information. Now it's clearer to me what the issue could be.

I guess the problem is on the server side as you already got a connection and some logs during the attempt of receiving a file.

When googling for "425 Unable to set up passive listening socket" I get a lot of resources, for example: https://www.ibm.com/support/pages/ftp-425-error-unable-open-data-connection 

I think you have to get in contact with the responsible support team of the FTP server to solve the issue.
