Codex Connection Errors & Stream Fixes

When a response stops halfway or a message never submits, first identify whether the failure affects one session, one client or the service. These guides separate interrupted streams from task creation and submission failures.

What to check first

• Save the exact error and note which client produced it.
• Check whether a new session fails in the same way.
• Match the error to a guide before changing network or account settings.

Connection troubleshooting guides

• Codex: stream disconnected before completion

  Ask Codex to continue once. If it disconnects again, compare a short prompt in a new session before changing settings.
