Initial requirements
Set up the es cluster as shown below：
However, the following anomalies are found:

So I rebuilt the es cluster, as shown in the following figure:
However, I found that in kibana, I still could not see the data of each es cluster in the blue box。
Is it because remote cluster cannot multilayer proxy?
