No Endpoint listening error?

I have been getting this error intermittantly since I launched the site (once every couple weeks). However now t开发者_开发百科hey have been more frequent, several each day. Strangely enough these recent ones all seem to be from various Mozilla broswers. I don't see how that would have anything to do with the issue though.

I have already checked the logs on the web server (GoDaddy) and WCF Server (local). I also checked the firewall on the WCF server. I am just at a loss of what to check next, any ideas?

Have you enabled WCF tracing on the client? If not, you could try it. It might reveal some extra information. You can do it like this:

<system.diagnostics>
    <sources>
      <source name="System.ServiceModel" switchValue="Verbose, ActivityTracing">
        <listeners>
          <add name="xml"/>
        </listeners>
      </source>
      <source name="System.ServiceModel.MessageLogging" switchValue="Verbose">
        <listeners>
          <add name="xml"/>
        </listeners>
      </source>
    </sources>
    <sharedListeners>
      <add name="xml" type="System.Diagnostics.XmlWriterTraceListener" initializeData="c:\path\to\logfile.svclog"/>
    </sharedListeners>
    <trace autoflush="true"/>
  </system.diagnostics>

This will log extensively, so make sure that you have diskquota for it. You need to use the service trace viewer program to view the generated log file. It comes with the windows sdk.
