求助：flink1.11以上版本在k8s集群上的部署问题！[阿里云实时计算 Flink版]

按照官方文档https://nightlies.apache.org/flink/flink-docs-release-1.12/deployment/resource-providers/standalone/kubernetes.html#session-mode 在kubernetes上部署flink1.11以上版本会出现奇怪的问题（1.10以前正常），提交作业后Dashboard会持续卡顿处于loading状态，始终显示不出job信息：

直到作业失败，且卡顿时间和数据源的并行度有关，并行度越高卡顿时间越久：

末尾附上两段报错信息，主要是一些心跳timeout之类的通信错误，但是在loading的时候Dashboard上仍然可以显示Taskmanager列表，点进去观察也没发现异常的GC停顿，而且如果是通信环境问题为什么1.10之前的版本没问题？

不知道是不是部署方式不对？下面是集群环境、部署文件和异常信息：
