Check if cluster-A cluster exists in nacos server

I met the same situation, subscribe is not working when clusters was set.
Maybe I can repait it.

[youzhixiaomutou]

clusters in notify reply is empty.

@tureo It works well with nacos server v2.4.1. But not work with v2.0.2 and v2.1.0.

@youzhixiaomutou Thank you, our Nacos server version cannot be upgraded, so our temporary solution is to temporarily not set the cluster value

Check if cluster-A cluster exists in nacos server

@binbin0325 Yes, I am certain that cluster-a exists in Nacos, and here are some details and solutions for reproducing it
