TL;DR

The issue may be resolved by checking the Codex App's configuration or network settings to ensure proper connectivity to the backend API.

Guidance

• Verify the URL https://chatgpt.com/backend-api/codex/responses is accessible and not blocked by any firewall or proxy settings.
• Check the Codex App's subscription status to ensure it is active and valid, as the "plus" subscription might have specific requirements or restrictions.
• Investigate the cf-ray: 9ef4d8725d06a6c8-DEL header to see if it provides any clues about the issue, potentially related to Cloudflare or content delivery network (CDN) settings.
• Try to reproduce the issue with a different network connection or environment to isolate if the problem is specific to the current setup.

Notes

The lack of information about the platform and additional details makes it challenging to provide a more specific solution. The issue might be related to the Codex App's version, subscription, or network configuration.

Recommendation

Apply workaround: Given the uncertainty around the issue, it's recommended to try workarounds such as checking network settings, verifying subscription status, or testing with a different environment before considering an upgrade or more invasive changes.
