Conversation
Token-credential uploads can briefly receive data-plane authorization errors while access to a newly created storage account propagates. Retry only those responses for a bounded interval while preserving immediate failure for shared-key and unrelated errors. Related: OCPBUGS-99762

Summary
Reliability rationale
The failure mode has recurred in Azure installer CI job history, including the current development line, rather than being a one-off report. A bounded retry addresses the authorization-propagation window and is intended to reduce avoidable installation failures and repeat CI work while preserving fail-fast behavior for genuine permission errors.
