openclaw - 💡(How to fix) Fix [Bug]: openai-codex provider blocked by Cloudflare (403 CF mitigation active) on valid OAuth token [1 participants]

TL;DR

The openai-codex provider can be fixed by implementing a workaround to mimic browser-like requests, as the ChatGPT backend endpoint is blocking headless HTTP clients due to Cloudflare mitigation.

Guidance

• Verify that the OAuth token is valid and correctly exchanged for a token, as the issue is not with token generation but with the API endpoint blocking headless clients.
• Investigate using a library or tool that can simulate browser-like requests, such as adding headers that mimic a browser or using a headless browser library, to bypass Cloudflare mitigation.
• Consider using a paid fallback or alternative model to ensure system functionality in environments without paid fallbacks.
• Review the OpenClaw documentation and OpenAI Codex provider settings to see if there are any existing workarounds or configuration options to address this issue.

Example

import requests

# Add headers to mimic a browser
headers = {
    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3',
    # Add other browser-like headers as needed
}

# Use the headers with the request
response = requests.post('https://chatgpt.com/backend-api/conversation', headers=headers)

Notes

This workaround may not be foolproof, as Cloudflare mitigation can be complex and subject to change. Additionally, using a headless browser library may introduce additional dependencies and complexity.

Recommendation

Apply workaround: Implementing a browser-like request simulation is the most likely solution to bypass Cloudflare mitigation and restore functionality to the openai-codex provider.
