问题自查:

1、后台响应日志正常

2、查看nginx接入日志发现499错误

49.235.73.44 - - [22/Mar/2021:16:05:01 +0800] "POST /wechatCallback/1/?signature=361638e38d9965134351ba66f694912d432a31ed&timestamp=1616400296&nonce=522676474&encrypt_type=aes&msg_signature=28ed7f58af3c6d08fd035aa3f2f5897b6ef4ae4e HTTP/1.1" 499 0 "-" "Mozilla/4.0" "-"

此类信息出现非常频繁，大约10%的请求会出现该错误。

3、根据排查指导#附录3：nginx配置和排查指引

https://developers.weixin.qq.com/doc/offiaccount/Basic_Information/Warning_Message_Troubleshooting_Guide.html

发现如下描述: 499: 则是客户端的问题，请联系微信团队。 此错误少见。

因此特将此问题反馈给平台，望及时解决。谢谢！
