PO 7.5: inbound proxy - Unable to contact target server

Dear experts,

I have a scenario SFTP --> SOAP receiver.
It works for small messages but we had a message yesterday that had 744 KB and the error I get in the message monitoring is:
SOAP: Call failed: Error receiving or parsing request message:
java.lang.RuntimeException: Error while silently connecting:
Unable to contact target server <our S/4 system>.

The receiver channel looks like this:

The message in ERP SXMB_MONI looks like this:

Are there settings I have to do in SXMB_ADM? It currently looks like this:

I thought the engine could easily process files with a few megabytes. Thank your for any ideas on this.

Best regards, Peter

    • Hello Michal,

      I finally went ahead and set the timeout settings as follows:

      XMBWS.ConnectTimeout 10000
      XMBWS.ReadTimeout 900000
      XMBWS.Timeout 900000

      And now it works. I was able to process one message with 1500 lines. It took about 6 minutes but it was successful.

      I accepted your original answer - thank you again for pointing out the right direction.

      Best regards, Peter
