Elasticsearch + SW 6.4

Moin!

Ich versuche mich gerade auf meiner Testing-Umgebung an Elasticsearch. Dieses ist nach Doku eingerichtet und ich habe (zum Testen) einen Node laufen, was der folgende Befehl mir bestätigt:

root@SERVER.TLD:/# curl -ku elastic:$ELASTIC_PASSWORD https://localhost:9200/_cat/nodes
172.19.0.2 26 90 7 0.30 0.39 0.50 cdfhilmrstw * 73eea3ec62ef

Also habe ich die .env nach Anleitung angepasst, aber ich bekomme keine Verbindung:

root@SERVER.TLD:/#  bin/console es:index
    0 [>---------------------------] < 1 sec 48.5 MiB
In StaticNoPingConnectionPool.php line 64:

  [Elasticsearch\Common\Exceptions\NoNodesAvailableException]
  No alive nodes found in your cluster

es:index [--no-queue]

Ein Verbindungsproblem also. Meine .env sieht so aus:

SHOPWARE_ES_HOSTS="https://USER:PASSWORD@localhost:9200"
SHOPWARE_ES_ENABLED="0"
SHOPWARE_ES_INDEXING_ENABLED="1"
SHOPWARE_ES_INDEX_PREFIX="sw6"
SHOPWARE_ES_THROW_EXCEPTION=1

Nutzername und Passwort sind validiert. Nun ist guter Rat teuer - hat jemand eine Idee?
