项目连接emqx集群服务的虚拟IP时，启动可以正常连接并订阅主题成功，过一分钟后就断掉连，后续一直无法连接

改为集群中的单点ip没问题

用什么搞的虚拟 IP？ F5 还是？
麻烦提供一下 emqx 的 debug 日志。

根据官方配置的Haproxy 的虚拟IP,
日志如下：

这个是 haproxy 把他断开的。你一分钟没发任何包，被 haproxy 认为没心跳断开了。调高一点心跳：

 #option dontlognull  
  timeout connect 10000 
  # timeout > mqtt's keepalive * 1.2  
  timeout client 240s  
  timeout server 240s

非常感谢您！调整了这些参数目前不再有断开现象了
