You have an Azure Blob storage account.
Developers report that an HTTP 403 (Forbidden) error is generated when a client application attempts to access the storage account. You cannot see the error messages in Azure Monitor.
What is a possible cause of the error?

https://docs.microsoft.com/en-us/rest/api/storageservices/sas-error-codesThe HTTP 403 (Forbidden) error occurs when a client application tries to access a resource that it does not have access to. In this scenario, the error occurs when the client application tries to access an Azure Blob storage account.
The fact that the error cannot be seen in Azure Monitor suggests that it is not a configuration issue in Azure, but rather an issue with the client application or the way it is accessing the storage account.
Option A suggests that the client application is using an expired shared access signature (SAS) when it sends a storage request. A SAS is a URI that grants restricted access rights to a storage account. If the SAS has expired, the client application will not be able to access the storage account. This could be a possible cause of the error.
Option B suggests that the client application deleted and immediately recreated a blob container that has the same name. This is unlikely to be the cause of the error, as deleting and recreating a blob container with the same name should not affect the client application's ability to access the storage account.
Option C suggests that the client application attempted to use a shared access signature (SAS) that did not have the necessary permissions. This is another possible cause of the error. If the SAS does not have the necessary permissions to access the resource that the client application is trying to access, the HTTP 403 (Forbidden) error will be generated.
Option D suggests that the client application attempted to use a blob that does not exist in the storage service. This is also unlikely to be the cause of the error, as the HTTP 404 (Not Found) error would be generated instead.
In summary, the most likely cause of the HTTP 403 (Forbidden) error is that the client application is using an expired shared access signature (SAS) or a SAS that does not have the necessary permissions to access the resource it is trying to access.
