Error establishing SFTP


Good afternoon,

We are using the send file over node to put a file in an sftp.

But when we run it, it tells us this in the log:

com.appiancorp.suiteapi.process.exceptions.SmartServiceException: userMsg[error.sftp_conn=Error establishing SFTP connection. Confirm your hostname, username and password. See application server log for more details. Error Message: java.net.ConnectException: Connection timed out (Connection timed out)]

              

And it says that it is caused by

Caused by: com.jcraft.jsch.JSchException: java.net.ConnectException: Connection timed out (Connection timed out)

                at com.jcraft.jsch.Util.createSocket(Util.java:349)

                at com.jcraft.jsch.Session.connect(Session.java:215)

                at com.appian.ps.plugins.sftpsmartservices.SFTPConfig.connect(Unknown Source)

                ... 527 more

Caused by: java.net.ConnectException: Connection timed out (Connection timed out)

Does anyone know what may be failing or what we can check?

A greeting and thanks in advance
