Azure Autoscaling block cannot find certificate

Question

I have the following situation: My azure application consists of 5 roles. One of those roles hosts the Autoscale block from Enterprise Library. This role is responsible for scaling the others up and down.

Now I followed the tutorial and added the Autoscale settings to the app.config and also added the services.xml and rules.xml.

The problem is that the autoscale logger (which works!) outputs this error over and over again:

Could not retrieve the instance count for hosted service with DNS prefix 'myCloudApp'. Microsoft.Practices.EnterpriseLibrary.WindowsAzure.Autoscaling.ServiceManagement.ServiceManagementClientException: The service configuration could not be retrieved from Windows Azure for hosted service with DNS prefix 'myCloudApp' in subscription id 'xxxxxxxxxxxxxxxxxx' and deployment slot 'Production'. ---> Microsoft.Practices.EnterpriseLibrary.WindowsAzure.Autoscaling.Security.CertificateException: The certificate with thumbprint 'xxxxxxxxxxxxxxxxxxxxx' in store name 'My' and store location 'LocalMachine' could not be found. at Microsoft.Practices.EnterpriseLibrary.WindowsAzure.Autoscaling.Security.CertificateHelper.FindCertificate(StoreName certificateStoreName, StoreLocation certificateStoreLocation, String certificateThumbprint, Boolean withPrivateKey, Boolean validOnly) at Microsoft.Practices.EnterpriseLibrary.WindowsAzure.Autoscaling.ServiceManagement.ServiceManagementClient.CreateFactory(StoreName certificateStoreName, StoreLocation certificateStoreLocation, String certificateThumbprint, Inspector inspector) at Microsoft.Practices.EnterpriseLibrary.WindowsAzure.Autoscaling.ServiceManagement.ServiceManagementClient.CallOperation[TResult](Func2 call, StoreName certificateStoreName, StoreLocation certificateStoreLocation, String certificateThumbprint, String exceptionMessage, String& requestId) --- End of inner exception stack trace --- at Microsoft.Practices.EnterpriseLibrary.WindowsAzure.Autoscaling.ServiceManagement.ServiceManagementClient.CallOperation[TResult](Func2 call, StoreName certificateStoreName, StoreLocation certificateStoreLocation, String certificateThumbprint, String exceptionMessage, String& requestId) at Microsoft.Practices.EnterpriseLibrary.WindowsAzure.Autoscaling.ServiceManagement.ServiceManagementClient.GetDeployment(String hostedServiceDnsPrefix, String subscriptionId, DeploymentSlot deploymentSlot, StoreName certificateStoreName, StoreLocation certificateStoreLocation, String certificateThumbprint) at Microsoft.Practices.EnterpriseLibrary.WindowsAzure.Autoscaling.ServiceManagement.ServiceManagementClientExtensions.GetDeployment(IServiceManagementClient client, HostedService hostedService) at Microsoft.Practices.EnterpriseLibrary.WindowsAzure.Autoscaling.DataPointsCollection.RoleInstanceCountDataPointsCollector.Collect(DateTimeOffset collectionTime)

I replaced the actual thumbprint and subscription id with xxxxx.

I dont understand why it cannot access my cloud services. Do I need to do anything to this certificate?

Help is greatly appreciated!!

Answer 1

Did you actually upload the pfx (private key side) of the management certificate? This error indicates it cannot find the cert installed on the machine.
