Ask: The Azure Event Hub is inactive after the hub was created a couple hours.
I am the Azure noob, my Azure Event hub has issue which the status is keeping not active after the hub was created, I have waited a couple hours but the status did not change, how can I fix the problem? I have referred the Quick Start Create a Event Hub but nothing help. Does it a common issue or some problem is on Azure now? or I have missed something while the hub was creating?
Solution: Finally, the issue has fixed by Azure self, now I can try to use the Event Hub, thank you again for your helping :)
