Exception and no alive nodes found

[DevXeni]

Hi!
I'm trying to install smile/elasticsuite, I use amazon aws elasticsearch v5.5,
I use endpoint AWS ES:

smile/smile_elasticsuite_core_base_settings/servers ***us-east-1.es.amazonaws.com

and

smile_elasticsuite_core_base_settings/es_client/enable_https_mode 1

because endpoind supports https.

All steps described in the documentation are passed, exept

bin/magento setup:upgrade

On this step, after few minutes, I've got a message: "No alive nodes found in your cluster".

But I can connect to endpoint

curl -XGET 'https://***us-east-1.es.amazonaws.com

and there is all plugins installed:

curl -XGET 'https://***us-east-1.es.amazonaws.com/_cat/plugins?pretty'

and AWS ES 5.5 supports

/_termvectors (Index only)

Why I've got this message "No alive nodes found in your cluster"?

Additionally, in var/report files was found:

Please upgrade your database: Run "bin/magento setup:upgrade" from the Magento root directory. The following modules are outdated: Smile_ElasticsuiteThesaurus data: current version - none, reqrequired version - 1.1.0 Smile_ElasticsuiteVirtualCategory data: current version - none, required version - 1.1.0

Please, maybe you can provide explanation?
Thank you for your excellent work :)

Is your endpoint exposed on port 80 ? Looks like you do not specify the port 9200 when accessing it through curl.

[DevXeni]

curl -XGET https://***.us-east-1.es.amazonaws.com:9200
Got nothing

but

[ec2-user@ip-10-0-19-247 ~]$ curl -XGET https://***.us-east-1.es.amazonaws.com
{
  "name" : "hodDSqF",
  "cluster_name" : "787466657098:***",
  "cluster_uuid" : "EJ2C9i3sQuSkHDgsIfiTCg",
  "version" : {
    "number" : "5.5.2",
    "build_hash" : "Unknown",
    "build_date" : "2017-10-18T04:35:01.381Z",
    "build_snapshot" : false,
    "lucene_version" : "6.6.0"
  },
  "tagline" : "You Know, for Search"
}

Seems like no need any port spec.
80 port - No, 443 (ssl) is used.

I am actually able to reproduce your issue.

I have a working ES instance on an https host, reachable via cURL, but not by Elasticsuite.

I am investigating and will keep you in touch.

Hi, just now, I checked dependent module elasticsearch/elasticsearch and this problem caused because that module setup default port to 9200 if it was not specified. Therefore, I specify the port as mydomain.com:443 and all works fine.
This issue not about smile/elasticsuite module at all.
Thank you and have a nice day!
Closed.

Yep,

I was about to answer that I went to the same conclusion, you have to specify the port 443 because having the scheme set to https is not enough.

Glad to see this one solved.
