I have been trying to configure Elasticsearch in the Magento installation for a few days but I can’t get it to work completely, I see it close but there is always something that fails.
I installed Magento disabling this module but now I want to do it right and enable it again.
The server I am working on has Plesk installed and SSL active. It works in such a way that NGINX handles requests and sends them to Apache.
I have Elasticsearch configured and active on port 9200
systemctl status elasticsearch -> active
I have configured nginx to work correctly with SSL:
If I make a request without a user or password, it returns Error 401 (correct):
curl -i https://xx.xx.xx.xx:8080/_cluster/health
HTTP/1.1 401 Unauthorized
Server: nginx
Date: Wed, 14 Dec 2022 14:12:08 GMT

If I add the username and password to the request, it answers correctly:
curl -i -u user:password https://xx.xx.xx.xx:8080/_cluster/health
HTTP/1.1 200 OK

{"cluster_name":"elasticsearch","status":"green","timed_out":false,"number_of_nodes":1,"number_of_data_nodes":1,"active_primary_shards":2,"active_shards":2,"relocating_shards":0,"initializing_shards":0,"unassigned_shards":0,"delayed_unassigned_shards":0,"number_of_pending_tasks":0,"number_of_in_flight_fetch":0,"task_max_waiting_in_queue_millis":0,"active_shards_percent_as_number":100.0}
However, in the magento administration section (Stores -> Configuration -> Catalog) when trying to put this configuration, the message appears
No alive nodes found in your cluster
What am I forgetting?
MORE INFO
netstat -an | grep 9200
tcp6 0 0 :::9200 :::* LISTEN
tcp6 0 0 xx.xx.xx.xx:9200 xx.xx.xx.xx:51762 TIME_WAIT
Netstat returns two services, I don’t know if this may be influencing.
