Issue

The Codex Windows App suddenly started timing out during model thinking / request processing.

The app itself can still open normally. I can access the basic UI and open local projects, but when Codex starts thinking or tries to process a request, it often times out. Remote pairing / reconnect also fails or times out.

This was working before, then suddenly started failing.

What I already tried

• Repair/reset Codex App from Windows Settings
• Uninstall/reinstall Codex App from Microsoft Store
• Clean up Codex App remnants
• Clear local Codex config and sign in again
• Restart Windows
• Update the ChatGPT mobile app
• Confirm the same ChatGPT account and same workspace are used
• Try mobile pairing again

Expected behavior

Codex should connect normally, process requests, and allow mobile pairing/reconnect.

Actual behavior

Codex keeps timing out during model thinking / request processing. Mobile pairing and reconnect also fail or time out.

Notes

The app UI itself is still usable, so this does not look like a complete app startup failure. The problem seems to happen when Codex needs to connect/process a request or when Remote Control pairing/reconnect is attempted.

What steps can reproduce the bug?

1. Open the Codex Windows App.
2. Sign in with a ChatGPT Plus account.
3. Open an existing local project or start a new Codex conversation.
4. Send any normal request that requires Codex to think/process a response.
5. Wait for the model thinking/request processing step.
6. The request eventually times out.
7. Try Remote Control / mobile pairing or reconnect.
8. Mobile pairing/reconnect also fails or times out.

The app UI itself still opens normally, and basic UI operations still work. The timeout happens when Codex needs to process a request or connect for Remote Control.

What is the expected behavior?

Codex should connect normally, process requests during model thinking, and return a response without timing out.

Remote Control should also allow mobile pairing/reconnect successfully when using the same ChatGPT account and workspace.

This issue started suddenly. Codex was working before.

I already tried:

• Repair/reset Codex App from Windows Settings
• Uninstall/reinstall Codex App from Microsoft Store
• Clean up Codex App remnants

• Restart Windows
• Update the ChatGPT mobile app

• Try mobile pairing/reconnect again

The app is not completely broken: it can still open, and basic UI operations work. The failure seems to happen specifically during model thinking/request processing and Remote Control pairing/reconnect.
