Hi,

This error means the call to Blob Storage failed, but StorageRequestFailedException is just the wrapper. To fix it, catch the exception and check ex.ErrorCode — it will tell you if it’s AuthorizationFailure, BlobNotFound, ContainerNotFound, etc.

Most common causes are:

Wrong connection string or expired key
Missing RBAC role (needs “Storage Blob Data Contributor” or similar)
Typos in container/blob name
Firewall or private endpoint blocking access

Check the exact error code and it should point you to the root cause.

Best regards! :)
