WCF over SSL - 404 error

Question

I had this same issue on my end. Your post helped me figure out what the issue was. here is my service model section. I discovered that the keys were the httpsGetEnabled then setting the bindingconfiguration I hope this helps.

<system.serviceModel>
        <behaviors>
            <serviceBehaviors>
                <behavior name="RequestImageBehavior">
                    <serviceMetadata **httpsGetEnabled**="true" />
                    <serviceDebug includeExceptionDetailInFaults="false" />
                  <dataContractSerializer maxItemsInObjectGraph="1073741824" />
                </behavior>
            </serviceBehaviors>
        </behaviors>
        <services>
            <service behaviorConfiguration="RequestImageBehavior" name="RequestImage">
                <endpoint address="" 
                          binding="wsHttpBinding" 
                          **bindingConfiguration**="HttpsBinding"
                          contract="IRequestImage">
                </endpoint>
                <endpoint address="mex" 
                          binding="mexHttpBinding" 
                          contract="IMetadataExchange" />
            </service>
        </services>
      <bindings>
        **<wsHttpBinding>
          <binding name="HttpsBinding">
            <security mode="Transport">
              <transport clientCredentialType="None"/>
            </security>
          </binding>
        </wsHttpBinding>**
      </bindings>
    </system.serviceModel>

I was dealing with this recently, and want to add a tweak. If you follow the above instructions, you'll be able to get the service to work with HTTPS, but not simultaneously work on both HTTP and HTTPS. To do that, you need to have two endpoint configuration nodes, one for each protocol as follows:

 <service name="MyCompany.MyService" >
    <endpoint address="" behaviorConfiguration="AspNetAjaxBehavior"
      binding="webHttpBinding" contract="MyCompany.MyService" bindingConfiguration="sslBinding" />
    <endpoint address="" behaviorConfiguration="AspNetAjaxBehavior"
      binding="webHttpBinding" contract="MyCompany.MyService" />
  </service>

(taken from my codebase, adjust behaviorConfiguration and binding as appropriate)

I just spent a few hours on this and it turned out my problem was the service name

<services>
      <service name="TimberMill.Web.Data.LogReceiverService">
        <endpoint binding="basicHttpBinding" bindingConfiguration="basicBinding"
                     contract="NLog.LogReceiverService.ILogReceiverServer" />
      </service>
    </services>

had to exactly match the similar entry in my *.svc file.

<%@ ServiceHost 
    Language="C#" 
    Debug="true" 
    Service="TimberMill.Web.Data.LogReceiverService, TimberMill.Web"
    Factory="Autofac.Integration.Wcf.AutofacServiceHostFactory, Autofac.Integration.Wcf"
    CodeBehind="LogReceiverService.svc.cs" 
%>

I'm not sure if it was related to my use of Autofac. It all was working fine under plain HTTP. Failed under HTTPS though.

Well I think so, I don't want to disturb anything now by testing in more detail lest I anger the WCF-Config gods and my config breaks again. YMMV.

In my case non of these answers helped.

Instead, I needed to add a duplicate <binding> section that has no name attribute set.

Here is the dump of the appropriate section of my service's web.config file:

<behaviors>
    <serviceBehaviors>
        <behavior name="ServiceBehaviour">
            <serviceMetadata 
                httpsGetEnabled="true" 
                httpsGetUrl="RemoteSyncService.svc"
                httpGetBindingConfiguration="bindingConfig" />
            <serviceDebug includeExceptionDetailInFaults="true" />
        </behavior>
        <behavior name="">
            <serviceMetadata 
                httpsGetEnabled="true" 
                httpsGetUrl="RemoteSyncService.svc" />
            <serviceDebug includeExceptionDetailInFaults="true" />
        </behavior>
    </serviceBehaviors>
</behaviors>

<bindings>
  <basicHttpBinding>
    <binding name="bindingConfig" maxReceivedMessageSize="2147483647" maxBufferSize="2147483647" transferMode="Streamed">
        <security mode="Transport">
          <transport clientCredentialType="None"/>
        </security>
      <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647"/>
    </binding>

    <!-- Add binding with EMPTY/MISSING name, see https://forums.iis.net/t/1178173.aspx -->
    <binding maxReceivedMessageSize="2147483647" maxBufferSize="2147483647" transferMode="Streamed">
        <security mode="Transport">
          <transport clientCredentialType="None"/>
        </security>
      <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647"/>
    </binding>
  </basicHttpBinding>
</bindings>

I do hope this might be helpful for someone, some day.
