Can't connect to AWS ES Service (Bad Request)

[pittersnider]

Summary of problem or feature request

I am trying to connect to an AWS elastic service through Symfony, as below:

However, I get this error:

My credentials (from picture #1) are like:

(host) stage-es.lewo.sms
(port) 443
(ssl) 1
(transport) AwsAuthV4
(aws_access_key_id) xxxxxx
(aws_secret_access_key) xxxxxxx
(aws_region) eu-central-1

Note: I use the same credentials to connect via FOSElastica and it works.

System details

OS: Linux
Symfony v3.4.23
PHP v7.1.26
ElasticSearch v5.6
Elasticsearch-php ~5.0

@pittersnider, could you please verify if the referenced issue of @y80x86ol is solving your problem? Or generally speaking is this issue still present?
