SFTP connect timeout

[wu_feng2]

Hello Expert,

I got in trouble with SFTP adapter.

The scenario is SOAP->PI->SFTP server.

I setup an SFTP server in my PC, test the SFTP adapter installed correctly or not.

The result is connect failed:

********************************************************************************************

Message could not be forwarded to the JCA adapter. Reason: com.jcraft.jsch.JSchException: Session.connect: java.net.SocketTimeoutException: Read timed out (local port 17340 to address 10.10.159.74, remote port 8000 to address 10.187.8.30)

Then，I try to use filezilla tool connect to SFTP server with the same IP，port，and user account. It is ok.

So, I think the firewall may block the connection.

I setup an FTP service in my PC with the same port 8000. The result is PI connect to my FTP Server successful.

So, Why the SFTP connection failed?

Hi Wu,

I think you more or less answered this question yourself.

"So, I think the firewall may block the connection."

Check with your network team/server team that TCP on port 8000 is allowed from you PI to your SFTP server.

Best regards,
Jacob

It's the network traffic controlling, cause that problem.

Thanks everyone's reply.

Hi Wu Feng,

is it solved?

increase the timeout period then it works as i had a similar issue in my project , sftp server has a problem while attempting the connection in the specified timespan.

hi Wu,

SFTP is working from your PC is ok, but check with PO server that FTP address is blocked, check SFTP is reachable from PO server with Network Firewall allowed.
