I have a Jhipster monolithic (React/Java Springboot) application, compiled as an executable jar. I have dropped the jar in a folder on an Amazon EC2 instance. I believe the application builds correctly. I am provided an internal IP (or localhost) that I can access the site internally. However, I do not know how access this external to the server.
I am assuming that I should be using the EC2 instance public url with a port number. I.e. ec2-[specific container details omitted].compute-1.amazonaws.com with :80 or :8080 or :9000 or :443.
I have tried all of these ports. I have verified that these ports are exposed via my security policies. Every tutorial I have read stops before this step.
