Frequent Interruptions in Graph API Subscriptions for MS Teams — Messages Not Received

Question

We are using the Microsoft Graph API to integrate with Microsoft Teams by creating subscription webhooks following this guide:

Create Subscription - Microsoft Graph.

We set the subscription to last for one hour, renewing it every 30 minutes, and have configured an Azure resource as per licensing documentation.

However, recently we’ve been facing issues where the subscription is created and updated without errors, but notifications either don't arrive or fail for some messages.

• The service is configured according to the documentation, and the issue happens too frequently to be random.
• Throttling or network issues seem unlikely, as everything runs in Microsoft's cloud.

Does anyone have ideas on what could be causing these interruptions or how to resolve them? What logs or parameters should we check for further diagnostics?
