Issue connecting SAP ECC and HCI to trigger IDOC

Hi Experts,

I followed the below mentioned blog and configured in my system. I am getting error in ECC as Status 02(Problem with SOAP class).

https://blogs.sap.com/2016/08/09/hci-hcp-is-idoc-adapter-deciphered-part-1-trigger-idoc-from-sap-to-hcc-using-basic-authentication/comment-page-1/#comment-364584

Also, I cannot see any logs in HCI and no messages in Message Monitoring in HCI.

In RFC destination, when testing the connection getting the below status –

In the IDoc Sender Channel we have the below screen. Do we need to enter any user credentials(deployed artifacts?)

Not sure what is the issue, and what I am missing.

Please help.

Thanks,
