Issue in synchronous SOAP To Proxy

Hi All,

I am using PI 7.4 AEX single stack. I have configured SOAP to Proxy synchronous web service Scenario.

I am using Soap -ui to test end to end. I can see call is coming to PI but its failing while using HTTP destination to trigger the proxy in ECC.

Below is the screen shot of message log created in PI. Please suggest what could be the reason of this error.

Thanks,
