The Codex app is not working for me. When I send any prompt, even a very simple one like “привет”, the app gets stuck reconnecting.

It repeatedly shows:

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

Then it fails with the following error:

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

This happens consistently and prevents me from using Codex at all.

What steps can reproduce the bug?

Steps to reproduce:

1. Open the Codex desktop app.
2. Start a new chat/task.
3. Send a simple prompt, for example: “привет” or “hello”.
4. Wait for the response.
5. The app starts reconnecting multiple times.
6. After several reconnect attempts, it fails with:

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

I tried the following, but the issue still happens:

• Logging out and logging back in
• Reopening the app
• Reinstalling the Codex app
• Creating a new chat/task
• Refreshing/retrying
• Trying very short prompts
• Trying with VPN changes / network changes

The issue is not related to a specific repository or prompt because it happens even with a simple message.

What is the expected behavior?

Codex should respond normally to the prompt instead of repeatedly reconnecting and failing with a stream disconnected error.

Additional information

I can provide screenshots if needed. The screenshot shows Codex repeatedly reconnecting from 1/5 to 5/5 and then failing with the stream disconnected error.

The issue happens even with a very short prompt, so it does not appear to be caused by context size, token limit, or a specific repository.
