Tasks are stuck in PENDING state or the alert "Nerdio Manager has not been able to check-in with our billing system" is displayed at the top of the page.
App Service WebJob is not running or has failed.
Restart the WebJob or App Service:
Go to Azure portal, find your App Service (should be in this format: nmw-app-xxxxxx) and open it, go to WebJobs and make sure that "provision" job is running. If it isn't, start it.
If the WebJobs table reports a status of "running", restart the App Service and wait 5 minutes.
Check the WebJobs again and ensure the status reports running again.
