QuickBooks Web Connector always returns a 404 error

_x000D_ _x000D_ I have created a WCF service endpoint for my QBWC to call. I have exposed to over HTTPS and implemented the contracts. clientVersion authenticate closeConnection connectionError getLastError receiveResponseXML sendRequestXML serverVersion The connector has the following QWC files: QuickBooks Integrator https:///QuickBookConnector.svc Used to integrate with Quickbooks install http:// depQB {GUID} {GUID} QBFS 2 false 0xF The connector fires off and calls serverVersion, cientVersion and then authenticate. After authenticate it says "Authentication failed." However in the web service I am not even checking username and password yes. And this is what I get in the logs. 20150811.17:07:20 UTC : QBWebConnector.SOAPWebService.do_serverVersion() : * Calling serverVersion(). 20150811.17:07:20 UTC : QBWebConnector.SOAPWebService.do_serverVersion() : Actual error received from web service for serverVersion call: .

The request failed with HTTP status 404: Not Found.* More info: StackTrace = at System.Web.Services.Protocols.SoapHttpClientProtocol.ReadResponse(SoapClientMessage message, WebResponse response, Stream responseStream, Boolean asyncCall) at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters) at QBWebConnector.localhost.WCWebServiceDoc.authenticate(String strUserName, String strPassword) at QBWebConnector.localhost.WCWebService.authenticate(String strUserName, String strPassword) at QBWebConnector.SOAPWebService.authenticate(String UserName, String Password) at QBWebConnector.WebService.do_authenticate(String& ticket, String& companyFileName) Source = System.Web.Services Now it is saying it gets a 404 error. However, I can take the exact same URL that is the "AppURL" section of the QWC file and put it in a browser and it loads the service page. SO a browser can hit the service URL but QBWC can't? Any ideas?
