New tenancy (Nov 2, 2026, Osaka): OCI API call returns 401 NotAuthenticated — keys verified correct

in Identity and Access Management 4 comments

Hello,

I created a new OCI tenancy on November 2, 2026 (home region: Osaka / ap-osaka-1, Free Trial).
The OCI Console works normally, but EVERY OCI API request has failed with 401 NotAuthenticated
from the very first attempt, and it has never succeeded once — this has continued since creation and is still failing on Nov 5.
As a Free Trial account I cannot open a formal support request, so I am posting here.
My tenancy and user OCIDs, and a sample opc-request-id, are available on request.

Details:
- Only one user in the Default identity domain (the tenancy administrator), status Active.
- API key 1 fingerprint: 3c:1f:0c:62:27:ce:8c:41:44:78:5d:8c:92:77:6c:f4 (created Nov 02, 2026, 10:16:07 UTC)
