Codex Desktop: resume conversation and model settings fail when cloud config bundle times out

Summary

Codex Desktop repeatedly fails to resume remote conversations and sometimes fails when updating model/reasoning settings.

The error is:

failed to load configuration: timed out waiting for cloud config bundle after 15s

This looks like a Desktop-side config sync/load problem. CLI switching works, but the Desktop path fails.

Environment

• Codex Desktop on macOS
• Remote conversation resume in Desktop
• Model/reasoning setting updates in Desktop settings
• CLI path appears unaffected

Steps to reproduce

1. Open Codex Desktop.
2. Try to resume a remote conversation.
3. Or open model settings and change default model / reasoning effort.
4. Observe repeated failure.

Actual result

The app logs repeated failures such as:

method=thread/resume
method=config/batchWrite
Failed to update model and reasoning effort
failed to load configuration: timed out waiting for cloud config bundle after 15s

Expected result

Desktop should load the cloud config bundle, resume the conversation, and persist model/reasoning settings successfully.

Notes

• The issue is reproducible across multiple attempts in the same session.
• This looks different from a model/provider failure; the failure happens before the conversation resumes or settings persist.
• CLI can still switch models successfully, which suggests the bug is specific to the Desktop config/resume path.
