Sentry not working on Azure App

I am using Sentry free account for logging error in my application. The logging works fine on my dev environment but when I deploy app on Azure, errors are not pushed on sentry. I checked file logs and the Sentry client CaptureException method is working fine and returning a SentryId as well but when I check at, no exception is logged there.
It is an asp. net application.
DotNet Framework: 4. 6. 1
Sentry Client Version: 3. 9. 0. 0

I have checked my Azure logs and nothing found related to Sentry. Please suggest what can I do to debug my issue,
