I've restored a backup on a test machine, to check if I can reproduce a problem I recently had after an update.
The installation went fine, but if I try to access the portal I just get "HTTP Error 503. The service is unavailable."
Checking the event log, I see some errors like this:
Workflow host activation failed for workflow definition id : dc9515e6-8883-4101-96f4-23e19b66cb9f, version key: 197. Exception: Object reference not set to an instance of an object. at Microsoft.ResourceManagement.Workflow.Hosting.HostActivator.ActivateHost(ResourceManagementWorkflowDefinition workflowDefinition, Boolean suspendWorkflowStartupAndTimerOperations)at Microsoft.ResourceManagement.Workflow.Hosting.HostActivator.RetrieveWorkflowDataForHostActivator()
The service seems to be otherwise working, e.g. I can query objects with PowerShell cmdlets.
Any idea what the problem could be?
