SFTP Connection Timeout in Talend Cloud

MDVV — Thu, 10 Jul 2025 01:56:54 GMT

Hello Team,

I'm having a problem with the following:

I need to connect to an SFTP server.
My job in Talend Studio is as follows:

tFTPConnection--->tFtpDelete

and the connection configuration is:

Running it in Talend Studio works correctly, but when publishing it to Talend Cloud, it gives me a timeout error:

Exception in component tFTPConnection_1 com.jcraft.jsch.JSchException: timeout: socket is not established.

I've already tested the connection in Filezilla and it works correctly.
I've already tried increasing the timeout on the Talend connection.
I've already tried pinging and it responds correctly.

I'm not sure if I should create the connection from Talend Cloud or if the connection is migrated when I publish the job to the cloud.

Any suggestions? Has this happened to anyone?

Thanks in advance.

Hello,
Do you get the same behavior when running the job as a standalone job :
- On the Studio machine
- On the Remote Engine machine

Hello, thank you for your response.

* The job fails when running in Talend Cloud Management:

* The job runs correctly in Talend Studio:

The link mentions that to run a job in Talend Cloud Management, you don't need to build the job, just publish it, and that's what I've done,

I followed the steps to publish in Talend Cloud Management:

Publishing to Talend Cloud | Talend Studio Help

and I'm getting a timeout error. The job is simple: just an SFTP connection and file deletion.

I'm very confused.

Hello,

Using the java program testnet.jar you can download here :

testnet.jar

could you test to establish a connection to your SFTP server ?

For ex:

java -jar testnet.jar test.rebex.net 22

Program to execute on the Remote Engine machine

Kind regards
Denis

Hello @Denis_Segard ,

Thanks for the support.
After much research, I realize that Remote Engine version 2.9 does not support SFTP.
