Cannot connect to CRM Online instance RRS feed

  • Question

  • I created a sample app to connect to CRM online environment but I'm getting the bellow exception. 

    Value cannot be null. Parameter name: identityProvider

    at Microsoft.Xrm.Sdk.Client.ServiceConfiguration`1.AuthenticateOnlineFederationInternal(AuthenticationCredentials authenticationCredentials) at Microsoft.Xrm.Sdk.Client.ServiceConfiguration`1.Authenticate(AuthenticationCredentials authenticationCredentials) at SampleApplication.Controllers.HomeController.GetProxy[TService,TProxy](IServiceManagement`1 serviceManagement, AuthenticationCredentials authCredentials) at SampleApplication.Controllers.HomeController.Index()

    The strange thing is that it is working as expected on one of the servers we have, but throws the exception I mentioned when accessed from the other. Both machines are running Windows Server 2012 with Windows Identity Foundation 3.5 installed.  I'm using Microsoft.XRM.SDK v8.0.0.0 with .NET 4.5.2. Here's the code block:

    { var orgServiceManagement = ServiceConfigurationFactory.CreateManagement<IOrganizationService>(new Uri("https://************.crm4.dynamics.com/XRMServices/2011/Organization.svc")); var endpointType = orgServiceManagement.AuthenticationType;

    var authCredentials = GetCredentials(endpointType, "*******@********.onmicrosoft.com", "**********");

    var organizationProxy = GetProxy<IOrganizationService, OrganizationServiceProxy>(orgServiceManagement, authCredentials);

    organizationProxy.EnableProxyTypes(); organizationProxy.Authenticate(); } //rest of the code...

    And here's the essential part of the two used methods:

    private static AuthenticationCredentials GetCredentials(AuthenticationProviderType endpointType, string username, string pass)
    	var authCredentials = new AuthenticationCredentials();
    	authCredentials.ClientCredentials.UserName.UserName = username;
    	authCredentials.ClientCredentials.UserName.Password = pass;
    	authCredentials.SupportingCredentials = new AuthenticationCredentials();
    	authCredentials.SupportingCredentials.ClientCredentials = Microsoft.Crm.Services.Utility.DeviceIdManager.LoadOrRegisterDevice();
    	return authCredentials;
    private static TProxy GetProxy<TService, TProxy>(IServiceManagement<TService> serviceManagement, AuthenticationCredentials authCredentials)
       where TService : class
       where TProxy : ServiceProxy<TService>
       Type classType = typeof(TProxy); 
       if (serviceManagement.AuthenticationType !=
    	   var tokenCredentials = serviceManagement.Authenticate(authCredentials);
    	   return (TProxy)classType
    		   .GetConstructor(new Type[] { typeof(IServiceManagement<TService>), typeof(SecurityTokenResponse) })
    		   .Invoke(new object[] { serviceManagement, tokenCredentials.SecurityTokenResponse });
       //other staff here

    I would appreciate any help! Thanks!

    Update: I have tried one of the sample apps which ships with the SDK on the problematic server and got the below error:

    Unable to connect to the remote serverA connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond

    Then we have white listed all the IP Ranges listed here: https://support.microsoft.com/en-us/kb/2728473 plus the login.live.com IPs I was able to find,

    but this doesn't helped.

    Hi Andrii,

    Thanks for your response. I followed the steps in your blog and migrated my sample app to the easier approach but I got similar result or at least similar behavior. This time I get the below exception when trying to execute simple WhoAmIRequest:

    Object reference not set to an instance of an object.
    at Microsoft.Xrm.Tooling.Connector.CrmServiceClient.Execute(OrganizationRequest request) 
    This happens on only one of the two servers we have. It works fine on the other. Please share your thoughts?

  • Unfortunately I have no other ideas. Provided code works for any org I can reach.
