Which IDE are you using?

What platform is your computer?
Microsoft Windows NT 10.0.19045.0 x64
What issue are you seeing?
The VS Code Codex extension repeatedly enters a reconnect loop and fails to complete responses.
Symptoms:
- "Reconnecting... 1/5 → 5/5" loops continuously
- Eventually fails with:
"stream disconnected before completion"
- Response begins but disconnects mid-stream
- Retry loop does not recover
Key observation:
- This also happens in completely fresh chats / sessions
- So it does NOT appear to be related to large context size or long threads
What I already tried:
- Fresh chat/session
- Forked chat
- Switched between stable and pre-release extension versions
- Issue still persists
Versions tested:
- Pre-release: 26.5406.31014
- Stable: 26.406.31014
Example request ID from one failure:
fd0ab001-6841-4796-8cf8-5fc3d99a8789
What steps can reproduce the bug?
- Open Codex in VS Code
- Start a session or open a chat
- Send a prompt
- Response begins streaming normally
- Mid-response, the stream disconnects
- Extension enters reconnect loop:
- "Reconnecting... 1/5" through "5/5"
- Retry loop fails and response does not complete
Also reproduced in:
- Completely fresh chats
- Both stable and pre-release extension versions
What is the expected behavior?
Codex responses should stream normally and complete without entering repeated reconnect attempts.
If a temporary connection interruption happens, the extension should either:
- recover cleanly and continue the response, or
- fail once with a clear error
It should not get stuck in a reconnect loop where the response never completes.
Additional information
This was initially suspected to be caused by a very large long-running chat, but the same behavior was reproduced in a completely fresh chat/session.
That seems to rule out context size or my i3-5005U as a low power chip as the root cause.
This issue appears more likely to be related to streaming / reconnect handling in the VS Code extension or backend connection path.
