Question

I have dot net core 2.2 application which consuming NAV SOAP endpoint working fine in the IIS environment. I have upgraded to dot net core 3.1 where the SOAP endpoint not working giving the error "The HTTP request is unauthorized with client authentication scheme 'Basic'. The authentication header received from the server was 'Negotiate'."

While debugging I come to know Channel, Inner channel and State is not initialize properly in dot net 3.1 generally state should be open but it's showing faulted.

Exception -- system.servicemodel.communicationobjectfaultedexception.
