Creating SSL certificate

Hello,

By default, your environment is available to users at a subdomain of elasticbeanstalk.com. When you create an environment, you can choose a hostname for your application. The subdomain and domain are autopopulated to region.elasticbeanstalk.com. To route users to your environment, Elastic Beanstalk registers a CNAME record that points to your environment's load balancer. You can see URL of your environment's application with the current value of the CNAME

If you need HTTPS for your Elastic Beanstalk environment using the default domain, you will have to set it up manually using a self signed certificate. You can follow this post: https://medium.com/geekculture/installing-a-self-signed-ssl-certificate-on-aws-elastic-beanstalk-1d4acd2c0cd
