nginxconfig | C library for parsing and printing nginx.conf | Runtime Evironment library

I have aws ec2 with elastic ip and route53 with my domain and have nginx in server, this works fine but,

i have seen how other websites work, amazon.com udemy.com. If you access directly by public ip or public dns you throw an error. My question is how can I configure it to do the same.

example:
browser url by domain: amazon.com = ok
browser url by public ip: 52.222.137.64 = 400-403 error.
browser url by public dns: server-52-222-137-64.ams50.r.cloudfront.net = 400-403 error.

browser url by domain: example.com = ok
browser url by public ip: 124.34.32.245 = ok.
browser url by public dns: ec2-124.34.32.245.eu-west-3.compute.amazonaws.com = ok.

Thanks all for your help.

example is substitute for my domain, this is my config.

I'm new to AWS and trying to understand which version of NGINX I should be installing on my instance. I've found multiple options;

• Via EPEL as the blog entry
• Amazon's own (?) version as this answer
• The 2016 NGINX official tutorial

On my development environment (Centos VM) I used sudo yum install nginx. Having tried the EPEL route I don't get the same set up, in particular sites enabled/available is not created as part of the setup. I want to use nginxconfig.io which requires those. Which version of NGINX should i use for that?

I am trying to init container with existing configurations files I have. The files that I have are nginx.conf and ssl.conf. The volumes configuration is set like this:

I have been trying to install the RapidSSL certificate on my droplet on Digital Ocean. This droplet is running NGINX / Ubuntu 16.1 x64.

I was following this tutorial: https://www.digitalocean.com/community/tutorials/how-to-install-an-ssl-certificate-from-a-commercial-certificate-authority#install-certificate-on-web-server

But I arrived at the part where I need to edit "Nginx server block" :

I am trying to deploy my website to amazon ec2 using nginx,puma and capistrano i followed this tutorial https://medium.com/@henslejoseph/deployment-a-rails-app-to-ec2-using-bitbucket-and-semaphoreci-d539bea90db3 the application got deployed to server but when i trying to access it via browser by going to website url it says This site can’t be reached.The next thing i tried is checking the nginx and the puma logs i dont find anythig in nginx logs but in puma_access.log there is error Errno::EADDRINUSE: Address already in use - bind(2) for "0.0.0.0" port 3000.After this i tried checking if any process is using the port 3000 using lsof -wni tcp:3000 and netstat -an | grep 3000 but the output was empty seems there is no process attached to port. I am trying to debug it from 3 days but still clue less what is going.Any help is greatly appreciated I am just enclosing my all my config files for reference.
