Hi, We are building a cluster environment on Azure using Solr 9.7.0 and ZooKeeper 3.9.2. Regarding communication from SolrCloud to ZooKeeper servers, aside from the client port 2181, are there any other ports that need to be allowed?
In our previous environment with Solr 8.4.0 and ZooKeeper 3.5.7, there were no issues. However, in the new version, we are experiencing issues like the ZK Status not being displayed or delays. Could you provide information about any additional ports or protocols that may need to be opened in the Solr 9.7.0 and ZK 3.9.2 SolrCloud environment? Regards, Mingchun
