Answer 1

Looking into your endpoint using Nmap:

it appears that port 80 is closed, you need to open it either in your OS firewall or in AWS Security Groups

On the other hand port 443 is open which is default port for HTTPS so my expectation is that if you change "Protocol" in the HTTP Request sampler (or even better HTTP Request Defaults) you will be able to normally access your endpoint
