Probably title of this post summaries it well, but there is some detail worth explanation. I was developing an Azure Function app which was basically integrating data between CRM and another system. The major functionality of this application was complete and tested. Two weeks back when I came back from leave I found my application which was working fine before can’t connect to CRM. I was using
Microsoft.Xrm.Tooling assembly with the following code but now it started returning null:
public static IOrganizationService GetOrganizationService(ref TraceWriter log)
IOrganizationService _orgService = null;
string connectionstring = ConfigurationManager.AppSettings["connectionstring"].ToString();
CrmServiceClient conn = new Microsoft.Xrm.Tooling.Connector.CrmServiceClient(connectionstring);
_orgService = (IOrganizationService)conn.OrganizationWebProxyClient != null ? (IOrganizationService)conn.OrganizationWebProxyClient : (IOrganizationService)conn.OrganizationServiceProxy;
CrmServiceClient has two very useful properties
LastCRMException which were showing this error message:
Unable to Login to Dynamics CRMOrganizationWebProxyClient is nullOrganizationServiceProxy is nullOrganizationServiceProxy is null
Tried looking for solutions and found the following suggestions:
- In connection string try Orgnaization unique name instead of friendly name
- May be assembly version is not compatible or code/ connection string should be written differently
- Use ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12; before connection
but none of these worked in my case. I contacted Microsoft support and they confirmed there was no such update or roll out that might have caused this but the good thing is they were still willing to help 🙂
I tried different types of applications, environments and versions but no luck.
In last while testing the following code the error was a little more meaningful:
IServiceManagement orgServiceManagement = ServiceConfigurationFactory.CreateManagement(new Uri("https://myCrmInstance.crm5.dynamics.com/XRMServices/2011/Organization.svc"));
AuthenticationCredentials authCredentials = new AuthenticationCredentials();
authCredentials.ClientCredentials.UserName.UserName = “firstname.lastname@example.org”;
authCredentials.ClientCredentials.UserName.Password = “*********”;
AuthenticationCredentials tokenCredentials = orgServiceManagement.Authenticate(authCredentials);
OrganizationServiceProxy organizationProxy = new OrganizationServiceProxy(orgServiceManagement, tokenCredentials.SecurityTokenResponse);
Entity contact = new Entity(“contact”);
contact.Attributes[“firstname”] = “Yawer”;
contact.Attributes[“lastname”] = “Iqbal”;
var contactId = organizationProxy.Create(contact);
“The security timestamp is invalid because its creation time (‘2018-04-01T12:30:45.790Z’) is in the future. Current time is ‘2018-04-01T12:24:29.185Z’ and allowed clock skew is ’00:05:00′.”
Getting hint about time I found time on my machine is 6 minutes behind. What caused this time change I still don’t know but since it was the difference of just 6 minutes I couldn’t notice this change. Corrected time and everything started working as it was. I thought to do a little experiment and moved clock 6 minutes ahead of current time and as per expectation error was different:
An unsecured or incorrectly secured fault was received from the other party. See the inner FaultException for the fault code and detail.
and inner exception:
An error occurred when verifying security for the message.
