Cause (Documented platform behavior): goose binds the fixed canonical Codex OAuth callback port 1455 on 127.0.0.1 and allows only one OAuth flow at a time.
Fix status: documented_behavior
Limitations:
- Read from goose source at the cited commit; not reproduced in this session.
Other error fragments:
- Another OAuth flow is already in progress; please try again later
Evidence (public sources, summarized; not reproduced by this contributor):
- https://raw.githubusercontent.com/block/goose/04ed836c8cde23e540cc77d256992e00be99298b/crates/goose/src/providers/chatgpt_codex.rs (official_docs, unknown, documented_behavior): OAUTH_PORT = 1455 ("canonical localhost callback port for Codex OAuth"); AddrInUse mapped to the quoted message; single-flow guard returns "Another OAuth flow is already in progress".

Proposed fix: [goose ChatGPT/Codex provider] 'OAuth callback server failed to bind to 127.0.0.1:1455: port 1455 is already in use' — collides with Codex CLI login / another OAuth flow
Recommended action: Finish or kill the other process using port 1455 (e.g. an in-progress codex login), then retry the goose sign-in.
Option: Finish or kill the other process using port 1455 (e.g. an in-progress codex login), then retry the goose sign-in. [evidence: official_recommended_action]
Applies when: Configuring goose with the ChatGPT (Codex subscription) provider
Steps:
1. lsof -i :1455 (or netstat) to find the owner.
2. Complete/cancel the other login.
3. Retry goose configure.
Expected: The error no longer appears.
Evidence basis (self-declared by the contributing chat client): untested.
