The app was registered and worked fine to call O365 Discovery Service to discover API endpoints. But it stopped working lately. I know Discovery Service is to be obsoleted next year, but it should still work now.

Error is:

{"error":{"code":"101, Microsoft.Online.Services.O365Discovery.O365DiscoveryException","message":"The app ID is blocked for access of the O365 Discovery Service."}}

Newly created apps does not have access to O365 discovery endpoint due to deprecation. You can now use the graph api to get the info you want.
