Can't enable https in microgateway

Hello, As mentioned in the title, I attempted to deploy a microgateway instance with both http and https ports, however only http was successfully deployed. Despite this, I generated an SSL certificate and modified the config file config/system-settings.yml.
Still didn’t get the https

PS: I’m launching microgateway with custom config

Did you follow the microgateway documentation ?
