Subscriptions Endpoint always returns 500 error for single client

Question

Issue Summary:

We are experiencing an issue when interacting with the Microsoft Graph API subscription endpoint (https://graph.microsoft.com/v1.0/subscriptions) for a particular client. Specifically, when attempting to create, retrieve, or manage subscriptions via this endpoint, the request fails consistently with the following error:

HTTPSConnectionPool(host='graph.microsoft.com', port=443): Max retries exceeded with url: /v1.0/subscriptions/ (Caused by ResponseError('too many 500 error responses'))

This error suggests that the request is being repeatedly retried but is still returning HTTP 500 status responses from the server, indicating a server-side issue.

Steps Taken:

• We’ve implemented logging to capture more detailed request and response data, but the issue persists.
• Attempts have been made to interact with the subscription endpoint at different time intervals to account for potential temporary service issues, yet the same error is observed.
• Multiple retries do not resolve the issue, and we are hitting the maximum number of retries set by our client.

Hi @Sameer Rawat

This looks like an error thrown by the Graph server. I suggest you open a support ticket with Microsoft Support to get help from the API owner.

Hope this helps.
