Asunto: Codex unusable due to continuous reconnection loop and stream disconnections

Hello OpenAI Support,

I am experiencing a persistent issue with Codex that started on May 28, 2026 and is still occurring on May 29, 2026.

Environment:

• ChatGPT Pro
• Codex accessed through chatgpt.com
• Windows 11
• Google Chrome (also reproduced in other browser sessions)

Problem: Every Codex task enters a reconnection loop and never completes. The interface repeatedly shows:

Reconnecting... 1/5 Reconnecting... 2/5 Reconnecting... 3/5 Reconnecting... 4/5 Reconnecting... 5/5

After several attempts, the following error appears:

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

Impact:

• Codex is effectively unusable.
• Tasks fail before completion.
• The problem has persisted for more than 24 hours.
• Multiple retries produce the same result.

Troubleshooting already attempted:

• Refreshing the page
• Logging out and back in
• Using different browser sessions
• Verifying internet connectivity
• Retrying multiple times over two consecutive days

Please confirm whether this is a known service issue affecting Codex and whether there is an estimated time for resolution.

I have attached a screenshot showing the error.

Thank you.

What steps can reproduce the bug?

1. Launch Codex Desktop App version 26.519.81530.

2. Sign in with a ChatGPT Pro account.

3. Create a new conversation.

4. Enter any prompt, including very simple prompts such as:

   • hello
   • create a file named test.txt
   • explain recursion

5. Submit the prompt and wait for the response.

6. Codex begins generating a response but repeatedly enters:

   Reconnecting... 1/5 Reconnecting... 2/5 Reconnecting... 3/5 Reconnecting... 4/5 Reconnecting... 5/5

7. After several reconnection attempts, the request fails with:

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

Expected result: Codex completes the response normally.

Actual result: The response stream disconnects repeatedly and the task never completes.

Frequency: 100% reproducible since May 28, 2026.

Additional notes:

• Occurs with both existing and newly created conversations.
• Occurs with simple and complex prompts.
• Internet connection is stable.
• The issue has persisted for more than 24 hours.
• Screenshots attached.

What is the expected behavior?

No response

Additional information

The issue appears specifically related to the Codex backend endpoint: /backend-api/codex/responses

The behavior suggests that the response stream is being interrupted before completion, causing repeated reconnection attempts followed by failure.
