Hi Stephen,

You were right. Now I can ping and telnet Both ports, 9300 and 9200, from OPEL to MORRIS. Inbound rules were missing on the MORRIS firewall.

MORRIS has started:

[2021-02-19T11:41:11,134][INFO ][o.e.h.AbstractHttpServerTransport] [MORRIS] publish_address {10.146.114.89:9200}, bound_addresses {10.146.114.89:9200}
[2021-02-19T11:41:11,134][INFO ][o.e.n.Node               ] [MORRIS] started

For some reason, MORRIS was still unable to join the cluster. I remembered that I had experienced:
POST /_cluster/voting_config_exclusions?node_names=MORRIS

I ran:
DELETE /_cluster/voting_config_exclusions

And everything was fine:
GET http://morris:9200/

{
  "name" : "MORRIS",
  "cluster_name" : "AA-PT-Monitoring",
  "cluster_uuid" : "_UaiOyWxRSm3xgBYy62Vsw",

Thank you so much Stephen :slight_smile:
