WCF error - There was no endpoint listening at

I am developing a WCF service, running IIS6 on Window server 2003. I have built a test client to talk to the WCF service and I am getting the error below. I have been looking at this error for days and went through people's suggestions on forums, but with no luck. Any help would be appreciated, many thanks

There was no endpoint listening at https://webbooking.infodata.uk.com/Synxis/Synxis.svc that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.

System.Net.WebException: The remote server returned an error: (404) Not Found.
at System.Net.HttpWebRequest.GetResponse()

Answer

You do not define a binding in your service's config, so you are getting the default values for wsHttpBinding, and the default value for securityMode\transport for that binding is Message.

Try copying your binding configuration from the client's config to your service config and assign that binding to the endpoint via the bindingConfiguration attribute:

<bindings>
  <wsHttpBinding>
    <binding name="ota2010AEndpoint" 
             .......>
      <readerQuotas maxDepth="32" ... />
        <reliableSession ordered="true" .... />
          <security mode="Transport">
            <transport clientCredentialType="None" proxyCredentialType="None"
                       realm="" />
            <message clientCredentialType="Windows" negotiateServiceCredential="true"
                     establishSecurityContext="true" />
          </security>
    </binding>
  </wsHttpBinding>
</bindings>    

(Snipped parts of the config to save space in the answer).

<service name="Synxis" behaviorConfiguration="SynxisWCF">
    <endpoint address="" name="wsHttpEndpoint" 
              binding="wsHttpBinding" 
              bindingConfiguration="ota2010AEndpoint"
              contract="Synxis" />

This will then assign your defined binding (with Transport security) to the endpoint.
