Description

When NiFi is behind a proxy and has no direct access to Azure services via the internet, the Azure Storage processors fail if Service Principal or Managed Identity authentication is used.
These authentication methods need access to login.microsoftonline.com but no proxy can be configured for this at the moment.

Similar to the AWS and GCP credential services, add "Proxy Configuration Service" property in the controller service where the authentication parameters are configured.
Controller services: AzureStorageCredentialsControllerService_v12, ADLSCredentialsControllerService
