# 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. ## Prerequisites - An OCI account with `~/.oci/config` configured (see `oraclecloud-install-auth`) - **Python 3.8+** with `pip install oci` installed - **OCI CLI** installed (`pip install oci-cli`) for diagnostic commands ## Instructions ### Authentication Errors (401 NotAuthenticated) The 401 error has six distinct root causes. Run this diagnostic to isolate which one: ```python import oci import os def diagnose_auth(): """Diagnose OCI 401 NotAuthenticated errors.""" config_path = os.path.expanduser("~/.oci/config") # Check 1: Config file exists if not os.path.exists(config_path): return "CAUSE: Config file missing. Run: oci setup config" config = oci.config.from_file(config_path) # Check 2: All required fields present required = ["user", "fingerprint", "tenancy", "region", "key_file"] for field in required: if field not in config or not c...
