We have an issue when registering devices to Azure Notification Hubs and consequently devices don't receive notifications.
Context: We had a billing issue 2 months ago, and service was shutdown last Friday 19 of April. We updated the payment method and paid the 2 unpaid invoices on Monday 22 of April. However, the service is still unavailable. When trying to register an Android device to the Notification Hub, the following message appears: 'Unable to resolve host "NamespaceFamiliasPr0.servicebus.windows.net" No address associated with hostname' ann 'Unable to resolve host "NamespaceProfesoresPr0.servicebus.windows.net" and No address associated with hostname'.
We have tried the following possibilities but none have succeeded:

I’m sorry to hear that you’re experiencing this issue. I understand you had redeployed the resource group , but the name check-availability returns 'unavailable' .
Just to isolate, you may check- Azure Notification Hub Service RP is registered ( | unregister and then re-register), checkout the doc section for the steps : Register resource provider. (screenshot below)
If you haven't done, you may leverage Notification Hub diagnostics > from Azure Portal> Navigate to your Notification Hub app in the Azure Portal.
In the left navigation, click on Diagnose and solve problems - Review - “ diagnostics options' to fetch additional info: ( screenshot below)
As the name check-availability returned unavailable , you may test deploy with slight name modification, as per your requirement.
--Additionally, Diagnose dropped notifications in Azure Notification Hubs -This article identifies why notifications might get dropped or not be received by devices.
LC IBERICA, I'd followed-up with you privately. Please share the requested info (privately) for additional investigation.
Thank you for your answer, however none of the above options helped solving the issue. Still cant resolve the endpoints "NamespaceFamiliasPr0.servicebus.windows.net" and "NamespaceProfesoresPr0.servicebus.windows.net"
I'll reach-out to you privately to fetch additional details. In the interim, as mentioned, the name check-availability returned unavailable , you may test deploy with slight name modification for the resource, as per your requirement.
