Http statt https beim Installieren

Guten Tag!

Ich möchte Shopware 6 installieren und laufen dabei in einen „mixed content“ Fehler

Mixed Content: The page at ‚Setup | Shopware 6‘ was loaded over a secure connection, but contains a form that targets an insecure endpoint ‚Setup | Shopware 6‘. This endpoint should be made available over a secure connection.

Shopware 6 läuft in einem Caddy, PHP, MySQL Container hinter einem Caddy Reverse Proxy (den ich brauche, da weitere Caddy, PHP, MySQL Container auf dem virtuellen Server laufen)

Was ich bereits versucht habe

also eine framework.yaml symfony.yaml erstellt in /config/packages/prod

siehe hier

---
framework:
    trusted_proxies: '0.0.0.0/0, 10.0.0.0/8, 172.18.0.2/16'
    trusted_headers: ['x-forwarded-for', 'x-forwarded-host', 'x-forwarded-proto', 'x-forwarded-port', 'x-forwarded-prefix']

(/config/packages/prod/framework.yaml und /config/packages/prod/symfony.yaml haben den selben Inhalt)

Danach den Symfony Cache geleert

docker exec -it 71c6d07bacf6 php bin/console cache:clear

Warning: Failed to load plugins. Message: An exception occurred in the driver: SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo for lcmp-mysql-1 failed: Name does not resolve

 // Clearing the cache for the prod environment with debug false

Warning: Failed to load plugins. Message: An exception occurred in the driver: SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo for lcmp-mysql-1 failed: Name does not resolve

 [OK] Cache for the "prod" environment (debug=false) was successfully cleared.

Die IP des Reverse Proxies habe ich mit

herausgefunden

Berechtigungen wurden mittels
docker exec -it lcmpsw2-php-lcmp-sw2-1 chown -R www-data:www-data /var/www/html

angepasst.

Ich weiß echt nicht mehr, was ich hier tun soll, um das beheben.
Andere Shopsysteme konnten fehlerfrei installiert werden und laufen ohne Fehler mit dem selben Container Setup.

Hier eine Illustration zur Veranschaulichung

Ich bin für jeden Tipp absolut dankbar!
