Magento2 + Docker setup – frontend throws error: SSL_ERROR_RX_RECORD_TOO_LONG

At this point I can reach the Nginx welcome page via localhost:8001.

I then attached a terminal to the phpfpm container and run the Magento 2 installation commands in var/www/html:

composer create-project --repository-url=https://repo.magento.com/ magento/project-community-edition magento2

cd magento2

bin/magento setup:install --admin-firstname=Admin --admin-lastname=Admin --admin-email=test@test.com --admin-user=admin --admin-password=password --base-url=http://localhost --db-host=db --db-name=magento --db-user=magento --db-password=magento --base-url-secure=https://localhost --use-secure=1 --use-secure-admin=1 --use-rewrites=1 --language=de_DE --currency=EUR --timezone=Europe/Berlin --elasticsearch-host=elasticsearch --elasticsearch-port=9200 --language=de_DE --currency=EUR

Installation runs successful. I can see the database in phpmyadmin.

But I can’t reach the frontend. https://localhost:8001 and https://localhost:8001/magento2 throws this error: SSL_ERROR_RX_RECORD_TOO_LONG

Is one of these URLs even supposed to reach the frontend? Did I anything wrong or did I miss something in my setup?
