Oracle Cloud Common Errors

Overview

OCI API errors are notoriously cryptic. NotAuthorizedOrNotFound (404) could mean an IAM policy is missing or you typed the OCID wrong — the error is intentionally ambiguous for security. NotAuthenticated (401) covers six different config file problems. CERTIFICATE_VERIFY_FAILED has different fixes depending on your SDK language, OS, and whether you are behind a corporate proxy.

Purpose: A diagnostic decoder ring mapping every common OCI error to its real root cause and fix, with runnable diagnostic commands for each scenario.
