SubscriptionKeyNotFound error message generated each second

Question

Hello everybody,

I would want to resolve a strange situation. I found in Application Insight (Failure section) the following error message.

Error 401: Access denied due to missing subscription key. Make sure to include subscription key when making requests to an API.

This error message is generated 2 or 3 times by Second.

I didn't find the root cause of this situation. I just know the name of the API where the error is generated

Do you have a suggestion?

Thanks in advance

Hi there,

As a part of troubleshooting steps:

1) you can open a particular request id
2) ind a correlation id column, take it
3) use the correlation id in a trace table
