客户端被无故踢掉，EMQX 4.4.19

EMQX
1

我在使用EMQX4.4.19部署了服务器，使用物联设备（mqtt v3.3.1协议）连接该服务器。
物联客户端刚连接上没多久就会被broker踢掉，我对该设备开起了日志跟踪，确实显示borker会自动发送will。
下面是设备连接断开的日志跟踪，但是为什么会被踢掉并没有交代：

这里可以看出来是客户端主动断开了连接

这里可以看到will
但是服务器并没有收到，断开连接的消息，还有就是连接后会很快掉线，没到心跳时间就掉了

我发现了问题的跟节，我使用nginx反向代理的emqx，造成的连接断开问题。只有nginx哪里配置出的问题，暂时不清楚。
请问你们有nginx代理emqx的资料吗？
