* Try running sgadmin.sh with -icl (but no -cl) and -nhnv (If thats works you need to check your clustername as well as hostnames in your SSL certificates)
* Make also sure that your keystore or cert is a client certificate (not a node certificate) and configured properly in elasticsearch.yml
* If this is not working, try running sgadmin.sh with --diagnose and see diagnose trace log file)
* Add --accept-red-cluster to allow sgadmin to operate on a red cluster.
