判断节点能否访问 ChatGPT，在浏览器访问如下网址：

https://ios.chat.openai.com/public-api/mobile/server_status/v1

如果显示如下信息则可以：

{"status":"normal","message":null,"button_url":null,"button_title":null}

如果显示如下就是不可以：

{"error": {"message": "OpenAI services are not available in your country or region.", "error_type": "unsupported_country" } }

或者

{"cf_details":"Something went wrong. You may be connected to a disallowed ISP. If you are using VPN, try disabling it. Otherwise try a different Wi-Fi network or data connection. (2)"}

另外，ChatGPT 似乎验证手机时区和服务器IP所处的时区是否一致。
