Rodric, are you running a custom api gateway container ? The lines at [1] should fix the issue for you.
NGINX has its own internal DNS resolution for performance considerations. I'm curios what the content of "/etc/api-gateway/conf.d/includes/resolvers.conf" is inside the apigateway container. Also, in case you use a custom configuration file for OW, it's possible that the config doesn't include "resolvers.conf" and hence the DNS resolution doesn't work ?
