Still no fix for this? I am facing the same issue

PHP Version 8.1
elasticsearch/elasticsearch package version 8.2
Elasticsearch version 8.3

I think this is not a bug. This is a feature. @rockyru @MonkWang @creativedevs Elasticsearch PHP Client supporting just only for Elasticsearch. Not for the similar other solutions. :)

[rockyru]

hahaha. I need to fix this asap, I have a current deployment using laravel and I got stuck in here. Dang it!

[hkulekci]

Could you please execute and share your response with the following request :

curl -XGET 'http://localhost:9200' --verbose

I am getting the following response :

*   Trying 127.0.0.1:9200...
* Connected to localhost (127.0.0.1) port 9200 (#0)
> GET / HTTP/1.1

  },

}

As you see here, on the response header, there is X-elastic-product header as follow :

< X-elastic-product: Elasticsearch

Do you get on your server? The trait checks whether the requests coming from Elasticsearch server or not. Normally, with version 8.x, you need to get this header for all responses according to this PR. So, as I said before, this is a feature :D

This is what I am getting @hkulekci

• Trying 127.0.0.1...
• TCP_NODELAY set
• Connected to localhost (127.0.0.1) port 9200 (#0)

GET / HTTP/1.1
Host: localhost:9200
User-Agent: curl/7.58.0
Accept: /

• Empty reply from server
• Connection #0 to host localhost left intact
  curl: (52) Empty reply from server

[hkulekci]

So the problem is not the client, and your problem is the server. Somehow your server could not return the response correctly because / endpoint of Elasticsearch should return a response that seems to be my previous answer.

[rockyru]

@hkulekci but Kibana is working fine. It is just the Elasticsearch that is not returning anything when I try to access it with its default port. Any idea?

PHP Version 7.4 elasticsearch/elasticsearch package version 8.3.2 Elasticsearch version 7.8.0

@MonkWang I just noticed that you are using elasticsearch-php 8.x with Elasticsearch server 7.x. You need to use elasticsearch-php 7.x in order to connect to Elasticsearch 7.x. This is also reported in the README here.

[ezimuel]

@rockyru did you solve the issue? Are you using an official Elasticsearch server version? Elasticsearch 8 uses security by default, that means you need to use https and a valid credential to connect to it. You can read how to configure elasticsearch-php to connect to Elasticsearch 8 here.

[ezimuel]

I'm closing this issue. @rockyru let me know if you need to reopen it, thanks!

[rockyru]

hi @ezimuel , yep I've resolved the issue. Thank you!
