How to fix quota exceeded using Notification Hub

Henrik Barna 31

Hello,

When I try to register a new device I get 'The maximum number of devices has been reached or exceeded for the namespace.' error. I have a Basic subscription which allows 200K active users. When I check the Azure Portal I can see that I have 123K active registered users of the allowed 200K.

I don't understand what limit I exceeded. I am using this Notification Hub for several years and I didn't change anything recently.

Where can I check which limit I exceeded?

Thank you for the help in advance,

Henrik

@Henrik Barna Thank you for reaching out to Microsoft Q&A, apologize for any inconvenience caused on this.

If you are using the Notification hub is in Basic SKU, then the maximum number of active devices that you can have per Namespace is 200,000 as mentioned here in this pricing documentation.

You can check the number of active devices for a particular namespace in the overview section from the portal as shown below.

If you're seeing current active device is less than the threshold value (mention in the documentation) and you are facing quota exceeded error while creating the device registration.
Do help us with the NotificationHub Name,Namespace Name, last four digits of your subscription Id and timestamp (utc) to check and assist your further on this.

@Henrik Barna Thanks for your patience on this. I have check with Notification Hub engineering team and they have confirmed that this was happened due to recent code regression.

Engineer team has created a fix and deployed to all the regions as well. I would suggest you retry the operation registering a new device and do let us know if the issue still remains the same.

Feel free to reach back to me if you have any further questions on this.
