fulltextsearch Address of the Servlet needs to pass https, but converts to http

I am using ...aws.elastic-cloud.com:9243
the server applet is defined as
https://******************.eu-central-2.aws.elastic-cloud.com:9243/

So I enter exactly this string for "Address of the Servlet"
https://user:password@*****************.eu-central-2.aws.elastic-cloud.com:9243

the log files shows

:"Request: PUT http://user:password@*******************.eu-central-2.aws.elastic-cloud.com:9243/service_index/_doc/files%3A45307323?pipeline=attachment","userAgent":"--","version":"29.0.6.1","data":{"app":"fulltextsearch_elasticsearch","request":"{"[object]

which returns an error
{"reqId":"Ww4vhzZOpq7LjbtESUpN","level":3,"time":"2024-09-07T14:34:22+00:00","remoteAddr":"","user":"--","app":"fulltextsearch_elasticsearch","method":"","url":"--","message":"Retry 0: cURL error 56: Recv failure: Connection reset by peer (see https://curl.haxx.se/libcurl/c/libcurl-errors.html) for http://user:password@************.eu-central-2.aws.elastic-cloud.com:9243/service_index/_doc/files%3A45307323?pipeline=attachment","userAgent":"--","version":"29.0.6.1","data":{"app":"fulltextsearch_elasticsearch"},"id":"66dc66602286d"}

Hint:
this works
curl --user user:password -X GET "https://**************.eu-central-2.aws.elastic-cloud.com:9243/_cat/indices?v=true&s=index&pretty"

curl --user user:password -X GET "http://**************.eu-central-2.aws.elastic-cloud.com:9243/_cat/indices?v=true&s=index&pretty"

IMHO AWS elastic is not configured to handle http requests

as a quick fix I changed
lib/Vendor/Http/Discovery/Psr17Factory.php
to remove the error.
IMHO the prefix http or https must not be hard coded, but taken from the "Address of the Servlet"

176     private function buildUriFromGlobals(UriInterface $uri, array $server) : UriInterface
177     {
178         $uri = $uri->withScheme(!empty($server['HTTPS']) && 'off' !== \strtolower($server['HTTPS']) ? 'https' : 'http');
179         $hasPort = \false;
180         if (isset($server['HTTP_HOST'])) {
181 # fgf  $parts = \parse_url('http://' . $server['HTTP_HOST']);
182             $parts = \parse_url('https://' . $server['HTTP_HOST']);
183             $uri = $uri->withHost($parts['host'] ?? 'localhost');
184             if ($parts['port'] ?? \false) {
185                 $hasPort = \true;
186                 $uri = $uri->withPort($parts['port']);

Start in lib/Vendor/Http/Discovery/Psr17Factory.php, especially buildUriFromGlobals() around the HTTP_HOST parsing shown in the issue. Reproduce the request against an HTTPS Elasticsearch endpoint and trace how the servlet address becomes the logged request URL. Done means HTTPS endpoints are requested with the correct scheme without breaking HTTP configuration.
