wcf as windows service fails with error - wcf

Question

I wrote a self-hosted WCF service. When I run the server and the client, the client connects well. I rewrote the server as a Windows service. Now when I run the server and the client, the server is started, but the client fails upon request method with the error
The HTTP request is unauthorized with client authentication scheme 'Negotiate'. The authentication header received from the server was
Windows service is registered as LocalSystem. Server config:-

</client>
</system.serviceModel>
As I understand it, the main problem is that the server has become the service, but how to solve the problem I do not know. How can I resolve this problem?
