Research direction

Start with the uploaded thread 01a02589-a649-7e01-abba-77e47110a0b1 and reproduce the failure on Linux with Codex CLI 0.152.0. Investigate the WebSockets-to-HTTPS fallback and the reported 404 responses from the Codex endpoint; no source files or tests are named, so done would require identifying the cause and verifying that sessions connect successfully.
