so when i run the following commands. Why is it trying to proxy when those
nodes are down. Am i missing something?

java.net.UnknownHostException:
search-rules-solr-v1-2.search-rules-solr-v1.search-digital.svc.cluster.local:
It is trying to proxy because it's SolrCloud. SolrCloud has an internal
load balancer that spreads queries across multiple replicas when
possible. Your cluster must be aware of multiple servers where the
"rules" collection can be queried.
The underlying problem behind this error message is that the following
hostname is being looked up, and it doesn't exist:
search-rules-solr-v1-2.search-rules-solr-v1.search-digital.svc.cluster.local
This hostname is most likely coming from /etc/hosts on one of your
systems when that system starts Solr and it registers with the cluster,
and that /etc/hosts file is the ONLY place that the hostname exists, so
when SolrCloud tries to forward the request to that server, it is failing.
Thanks,
