CLI authentication fails with 401 Unauthorized after retry limit

Issue

The Codex CLI fails to authenticate, repeatedly returning 401 Unauthorized errors before exceeding the retry limit.

Error Output

■ exceeded retry limit, last status: 401 Unauthorized, request id: 99210d09997d307d-SEA
■ exceeded retry limit, last status: 401 Unauthorized, request id: 992103f58e774224-SEA

Behavior

• CLI attempts to connect/authenticate
• Each attempt fails with 401 Unauthorized
• After 5 retry attempts, the CLI exits
• Request IDs consistently end with SEA region identifier

Expected

CLI should successfully authenticate and execute commands.

Extra Notes

• I came across this using my typical internet, I even hopped onto a VPN to see if it was somehow that being the problem, nope, same thing/errors.

Request IDs from failed attempts: 99210d09997d307d-SEA, 992103f58e774224-SEA
