When your Azure subscription is disabled, you can no longer be used to create or manage Azure resources.
A subscription can be disabled for the following reasons:
- Your credit may have expired.
- You may have reached your spending limit.
- You have a past-due bill.
You need to confirm what exactly which of the possible reasons from the above.
