Error: Cannot obtain Metadata

When I deploy my service to a test server I am getting the following error when I am trying to use it through a wcf test client (although it works under localhost):

Error: Cannot obtain Metadata from http://internal/RegisterService/RegisterService.svc If this is a Windows (R) Communication Foundation service to which you have access, please check that you have enabled metadata publishing at the specified address.  For help enabling metadata publishing, please refer to the MSDN documentation at http://go.microsoft.com/fwlink/?LinkId=65455.WS-Metadata Exchange Error  
The remote server returned an error: (415) Cannot process the message because the content type 'application/soap+xml; charset=utf-8' was not the expected type 'text/xml; charset=utf-8'..HTTP GET Error

my web.config looks like this:

Interface:

namespace Services.WCF
{
    [ServiceContract]
    public interface IRegisterService
    {
       ...
    }
}

Service

namespace Services.WCF
{
    public class RegisterService : IRegisterService
    {
        ....
    }       
}

I have had a look through many posts with the same error but cannot find a solution. I have tried the following:

making sure the name of the service matches in the web.config and svc files
removing the mex binding
adding the base host
making sure the windows/temp folder has iis permissions

I can browse to the url and it looks ok but I just can't access it through the test client and was wondering what else I may be missing

Solution

After more browsing through the many posts on this subject, I have come across this post: Error: Cannot obtain Metadata from http ......?wsdl and tried the option of including the remote server's self signed certificate and this seems to have solved the problem for me. Removing the bindings for the https also worked
