Connection reset by peer Error called the java application in iflow

Hi experts,

I have a java application to create and update the master data of the S4H and is deployed in our scp.

Although it took only 17min 8sec when it is run by the postman for create/update the records 1000,

the following error occurs when its url is set up in the http receiver channel in our iflow.

error :javax.servlet.ServletException: Error during write of the response: , cause: java.io.IOException: Connection reset by peer

※I just the timeout setting of the http receiver channel is set up with 24hr(86400000ms) in our iflow.

Why the timeout error occurs only in our iflow although the java app response well.

Best regards,

Nyein.
