I am using AWS and I created an Instance in EC2 and created a SSL Certificate in Certificate Manager, I have a domain from whois.com which I was able to connect to my instance using Route 53.
I am now trying to install the SSL Certificate to my EC2 instance and have googled a bunch on tutorials on the subject, but they all are super confusing and don't seem to work, must of them say I need to use a Load Balancer, but either I am missing a step or something I am doing is wrong because the SSL certificate is not working, http works like a charm, https is not working at all.
Is someone able to point me in the right direction?
AWS do not allow the certificates to be downloaded for ACM public CA so you are limited with where it can be attached.
You cannot use a public ACM certificate directly in your EC2 instance. The following resources support attachment for HTTPS of your application:
Elastic Load Balancer (ALB, CLB or Network Load Balancer with a TLS target group)
CloudFront Distribution
API Gateway
If you do not want to use one of these resources then the following 3 options are available for you:
Use a free SSL CA to generate the SSL for your EC2 instance such as certbot
Purchase a SSL from another CA and install on your host
Use AWS ACM Private CA (Although this can be expensive)

I'm currently using AWS Route 53 for my domain (domain.com), I also generated an wildcard SSL cert from an external certificate authority (*.subdomain.com). I have installed the certificate in ACM.
My domain (domain.com) points to an ELB, which has 2 EC2 instances connected to it (1.1.1.1 and 1.1.1.2).
I want to create a subdomain (sub.domain.com) which points specifically to 1.1.1.2 and also has the SSL cert installed.
I've tried adding an A record in Route 53 with the subdomain pointing to the specific IP (1.1.1.2), this works, but when I add the https protocol it refuses to connect.
I pretty new with SSL and routing so any help is appreciated.
I believe AWS ACM does not support certificate for EC2. it only support for ELB, API Gateway and CloudFront. Please check https://docs.aws.amazon.com/acm/latest/userguide/acm-services.html
So you cannot connect with https on EC2 with certificate imported in AWS. You need to create own certificate manually on EC2.
Below note from AWS for ACM certificate on EC2
Public ACM certificates can be installed on Amazon EC2 instances that are connected to a Nitro Enclave, but not to other Amazon EC2 instances. For information about setting up a stand-alone web server on an Amazon EC2 instance not connected to a Nitro Enclave, see Tutorial: Install a LAMP web server on Amazon Linux 2 or Tutorial: Install a LAMP web server with the Amazon Linux AMI.
So far i did below configuration.
I hosted my site on EC2 AWS machine. Public ip and public DNS.
I can access my website by ip as well as public DNS.
I purchased domain name from GoDaddy. www.xxtrasc.com
On AWS I created Hosted Zone then map www.app.xxtrasc.com successfully.
Now i access my website directly www.app.xxtrasc.com
Next want to enable https
On AWS Certificate Manager order certificate with domain name *.xxtrasc.com
Did everything to add CNAME and all. I can see status gree colored Issued on ACM.
Now how i can attached this certificate to my web site so that i can access https://www.app.xxtrasc.com
You cannot use ACM to directly install your ACM Certificate on your AWS based website or application
https://docs.aws.amazon.com/acm/latest/userguide/gs-acm-install.html
You must use one of the following services:
Elastic Load Balancing
Amazon CloudFront
AWS Elastic Beanstalk
Amazon API Gateway
AWS CloudFormation
Please read the official doc : https://docs.aws.amazon.com/acm/latest/userguide/acm-services.html
So to install the certificate directly under apache2/nginx configuration you need to obtain the certificate from other third parties like Lets Encrypt, GoDaddy etc. you can read about that here - https://in.godaddy.com/help/manually-install-an-ssl-certificate-on-my-apache-server-centos-5238
On AWS I recommend using an ELB an placing your EC2 instances behind this ELB. This will allow you to select your ACM certificate from ELB itslef. Please read following doc to use classic load balancer with HTTPS https://docs.aws.amazon.com/elasticloadbalancing/latest/classic/ssl-server-cert.html
If you want to enable SSL on your site, you need to purchase SSL certificate. You can purchase it with Godaddy and then setup it on AWS server. Without SSL certificate, your https site won't work.
I set up EC2 Ubuntu instance, assigned an elastic IP, got example.com (domain) to the ec2 instance via Route53. Added an SSL certificate using ACM (certificate manager) which says 'issued'.
However, https://example.com raises ERR_SSL_PROTOCL_ERROR. http://example.com is working.
The security group has HTTPS port open.
What's wrong here? Why this is not working? Any clues? curl https://localhost -k shows local port 443 refused.
You can't deploy a public ACM certificate directly to an instance. The "issued" state, just means it's ready to be applied somewhere. It needs to be applied to a service that supports ACM like an ELB, API Gateway, or a CloudFront distribution, which can be used to offload SSL processing. See the faqs for an overview of how they can be used.
For a certificate directly on the instance, you can use letsencrypt to issue free, trusted certs.
Also, this assumes that you've configured the web server to listen on 443.
ACM can only be used with AWS resources such as Elastic Load Balancer, Amazon CloudFront distributions and APIs on Amazon API Gateway.
Make sure that you are using one the above services to serve your website content.
ACM cannot be directly used with EC2 instance, you either need Elastic Load Balancer or CloudFront distribution to used it.
I have an Application Load balancer and 1 EC2 instance currently behind it. Before, I was using another CA for receiving SSL certificates for my domain which was running on the EC2 with nginx. Now, I use SSL from Amazon's Certificate Manager for the load balancer's listener.
Should the domain's certificate be purchased individually on each EC2 instance for https connection to my application after moving it behind the ELB?
Is there any other way to establish https connection without using the separate certificates on the EC2 instances and with just the ACM on the load balancer?
You can use the same certificate on EC2.
But whenever you need to update the certificate you have to change in EC2.
If you have the EC2 in a private subnet (Not accessible to the internet)
you can use the self-signed certificate (self signed certificate nginx).
I encountered this problem and solved it by using the self-signed certificate.
You can use self-signed certificates on the EC2 instances to enable the load balancer to talk to your EC2 instances via https - the load balancer will not to certificate validation, so you do not need commercial certs.
I have dobut in AWS SSL.
I have launched instance in AWS.
Then I got Public IP of launched instance, which pointed to BLUEHOST (only for domain ) DNS record ( Type A).
when I tried subdomain.example.com is working in browser.
Then for SSL, I imported certificate key and crt in certificate manager.And
certificate status is ISSUED.
When I tried HTTPS in browser ( https://subdomain.example.com ) is not working
Any one guide me.
You cannot use the certificate provided by Amazon Certificate Manager(ACM) on EC2 instance. That can only be used with certain AWS services such as Elastic Load Balancer, CloudFront, API Gateway and Elastic Beanstalk.
If you want to use ACM, you can setup a ELB in front of your EC2 instance and have your certificate applied to ELB. When you are requesting for a certificate via ACM make sure to add *.example.com domain to protect your subdomain as well.
If you want to setup SSL on your EC2 instance itself, you can request for SSL certificates from a ssl certificate provider. There are many certificate providers, such as letsencrypt, sslforfree etc..
Here is a guide on how to install SSL certificates obtained from a certificate provider on your EC2 instance.
