以上为日志记录，经过2-3分钟后恢复正常了，但客户有反馈询问此事为何
1. api.weixin.qq.com提供多个IP作为接入，只配置1个，有单点故障风险。具体的对外服务IP列表可以从api接口获取，建议用户每周定期检查是否更新（接口文档：https://developers.weixin.qq.com/doc/offiaccount/Basic_Information/Get_the_WeChat_server_IP_address.html）
2. 最近对外IP会有裁撤操作，由于无法得知用户是否只配置单个IP，所以上述错误提示是预期之内，建议开发者尽快修改请求的IP。
3. 最后建议开发者：尽可能减少写死单个IP，尽可能使用域名解析，这有利于开放平台的优化和容灾部署，提高稳定性。
兄弟你现在好了吗？我还是报这个错，运行了一年多的程序，今天突然报这个
