emqx开启双向认证时，每分钟报错误信息

[grhsc]

emqx 5.1.4，安装在docker中，证书的创建是官方推荐的教程，而且通过客户端连接是确认可以使用的。
但是，一旦开启双向认证
fail_if_no_peer_cert = true或者在dashboard这里打开它

总是提示这样的错误信息，（当然这个信息似乎不影响正常使用，但每分钟2条也太频繁了）

请问是什么原因呀？困扰了好几天了

[JimMoen]

这部分日志看起来是客户端无法提供证书，所以 TLS 连接被拒绝了
参考文档：强制开启双向认证

[grhsc]

让我不理解的也是这一点，没有任何客户端连接呀，一旦打开这个监听，并设置 fail_if_no_peer_cert = true，就出现故障。

如果fail_if_no_peer_cert = false，就不会有故障信息，但就只是能是单向认证。

烦请指导，您提到的客户端是什么？内部的客户端吗，我确认没有外部客户端在连接它。
