[BUG][CODEX] - “stream disconnected before completion” on /backend-api/codex/responses (Feb 8, 2026)

Today (Feb 8, 2026) I started seeing intermittent failures while using Codex in ChatGPT. The response streaming stops before completion with this error:

stream disconnected before completion: error sending request for url (https://chatgpt.com/backend-api/codex/responses)

It happens across repeated attempts and prevents completions from finishing. Is anyone else seeing this today, and are there any known workarounds?
