The HTTP request is unauthorized with client authentication scheme 'Anonymous'. The authentication header received from the server was 'BASIC realm="Service-now"'.

I have tried to access SOAP service using c# code. I have selected basic authentication type but still it is taking Anonymous   and giving the following error:

"The HTTP request is unauthorized with client authentication scheme 'Anonymous'. The authentication header received from the server was 'BASIC realm="Service-now"'."

I 've got the same error, it seems a proxy issue , by replacing 

<security mode="Transport">
<transport clientCredentialType="None" proxyCredentialType="None"

with 

<security mode="Transport">
<transport clientCredentialType="Basic" proxyCredentialType="Basic"
