Issues in consuming WCF Service from a Azure PAAS Instance / Same thing works form a Console App

We are consuming WCF service from a console application with NetworkCredential(UserName && PWD) ,WSHTTPBinding.

When we call Service from Azure PAAS Service , we land into issue The HTTP request is unauthorized with client authentication scheme 'Negotiate'. The authentication header received from the server was 'Negotiate,NTLM'.

The Client Config for both PAAS Consumer, Console app looks exactly same. Not sure why the error is seen only in case of PAAS Consumer.

The reason is because the PaaS service is not in the same network of your WCF service or the credentials you're using are not valid.

For example:

you're using a valid / existing credential from your company network locally:

CONTOSO\thdotnet

When publishing to Azure and trying to use the same credentials it will fail unless you're using a VPN to allow your PAAS app to call the servers running in your company's network.
