I have a Vert.x server running on a single-instance Elastic Beanstalk server, and I'm trying to configure it to operate over HTTPS. I've set up the NS records and A record in AWS Route 53 to map the subdomain to my instance (pinging the subdomain succeeds), requested (and verified) the certificate from ACM, and opened up port 443 in my EC2 security group. But I can't quite figure out how to "attach" the certificate to my domain (if that's somehow necessary) or to get port 443 properly mapped to my Vert.x server.
Any tips will be appreciated.
