I'm try to enable SSL on my domain which points to my AWS instance I already create LB which connects to my instance. But when ever I try to access the domain using "https" I always get this error "refused to connect", what could be the reason for this?
If your domain has been acquired from AWS just request a SSL certificate on Amazon Certificate Manager.
aws acm request-certificate --domain-name example.com --subject-alternative-names www.example.com
(Go to step 4)
If your domain has been acquired outside AWS like GoDaddy or another service, first you need to adquired a SSL cert, for free SSL see Let’s Encrypt.
Import your certificate to Amazon Certificate Manager using cli
aws acm import-certificate --certificate file://cert.pem --certificate-chain file://chain.pem --private-key file://privkey.pem
Create your ELB and add this listeners:
See image
On ELB step 3 "Configure Security Settings", Choose an existing certificate from AWS Certificate Manager (ACM) and select your certificate (example.com) then continue your process.

I have AWS EC2 instance that sends the response using HTTP. The URL link is as below:
http://ec2-18-233-225-132.compute-1.amazonaws.com:3030/api/status
This works fine with the. S3 bucket after the deployment, but, the Cloudfront blocks request that are not comes using HTTPS. How do I make sure that HTTPS also work with this URL:
https://ec2-18-233-225-132.compute-1.amazonaws.com:3030/api/status
Thanks.
ec2-18-233-225-132.compute-1.amazonaws.com domain belongs to AWS, not you. This means that you can't have valid SSL certificate for it. You must have your own domain if you want to enforce https between CF and EC2.
Once you get your domain, you can use https://letsencrypt.org/ to get valid free SSL cert for it. Alternatively, you can front your instance with a load balancer, and get free SSL cert for your domain using AWS ACM. Then you associate the SSL cert with the LB.
For cloudfront https handling:
Create certificate in ACM. Update cloudfront distribution to use that certificate and set ssl/TLS.
https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/cnames-and-https-procedures.html#cnames-and-https-updating-cloudfront
for EC2 https handling: You need to open HTTPS port (443). To do that, you go to https://console.aws.amazon.com/ec2/ and click on the Security Groups link on the left, then create a new security group with also HTTPS available. Then, just update the security group of the instance.
After these steps, if it's still not working it is an application problem.
You have to configure the Security Group of that Instance...
At left side ,down below the EC2 dashboard ; you can see Network and Security-- then click on Security Group.Click on it ...Then edit inbound Rules...Add https ,port 443
I have a domain example.com and I want to have https access with subdomain my_subdomain.example.com with aws loadbalancer
I have loadbalancer open for 443 and have route53 cname my_subdomain.example.com point to my loadbalancer address. I can access the site in my ec2 using browser on my_subdomain.example.com however its not secure in browser
My ACM has approve for both example.com and *.example.com
Is there an extra step I need for https to work, because when I do it with a single server with nginx I use https://certbot.eff.org/lets-encrypt/ubuntufocal-nginx so I imagine I need a similar step
Can someone point me a direction?
Use AWS Certificate Manager for your certificate: it will provide a free certificate you can install on your load balancer. When you add the listener for port 443, step 3 will prompt you for a certificate, select 'Choose a certificate from ACM (recommended)'.
I try to configure https on ALB with default amazon subdomain: some-unique-path.elb.amazonaws.com
The problem is that I can't find how to generate the ssl certificate for this domain: Amazon Certificate Manager does not allow to generate certificates for amazonaws subdomains.
Is there any way to make it without buying custom domain and configuring it for ALB?
To use ACM you must have domain which you control. From docs:
Before the Amazon certificate authority (CA) can issue a certificate for your site, AWS Certificate Manager (ACM) must verify that you own or control all of the domain names that you specified in your request.
There are some free domain providers which you could maybe use, but you have to have domain under your control. You can't use some-unique-path.elb.amazonaws.com, because this is AWS-owned domain and you have no rights to it.
I am trying to host my frontend on AWS using cloudfront and backend on a EC2 behind a classic loadbalancer. I have imported my SSL certificate in ACM. Using ACM the certifcate has been installed on Cloudfront and classic Loadbalancer.
Cloudfront configuration:
Alternate Domain Names (CNAMEs) = mydomain.com
SSL Certificate = mydomain.com (xxx-yyy-zzz............)
Classic loadbalancer Configuration:
The load balancer is hosted on api.mydomain.com and SSL certificate installed using ACM.
Security group inbound rules configuration:
EC2 is running a Nodejs server listening on port 80. I haven't installed SSL certificate on EC2 because it was not mentioned in AWS documentation.
The home page opens up but when I try to login I get an error:
LoginSignUp.js:84 OPTIONS https://api.mydomain.com/user/signin net::ERR_INSECURE_RESPONSE
So the browser is blocking backend response because it is not secure. Do I need to install SSL certificate on EC2 also? Or did I make any configuration mistake?
It appears from your question that your SSL certificate is for mydomain.com and you are trying to request api.mydomain.com
Create a new ACM certificate that includes api.domain.com as either the domain name or as a Subject Alternative Name (SAN).
At a glance, the rest of the build looks correct.
I ask this because there are many resources out there for Lets Encrypt to auto renew and deploy (via Lambda) to ELBs. Doesn't AWS' Certificate Manager do the same thing?
https://aws.amazon.com/certificate-manager/faqs/
Says:
Q: What can I do with AWS Certificate Manager?
...
ACM manages certificate renewals and certificate deployment for you.
However the AWS docs don't talk about this at all.
So if I understand this correctly...
I request a cert
Verify the cert in my email
Manually deploy the cert
ACM will every year renew my cert and deploy my cert back to all the resources I deployed it to previously
Is this correct? Is there documentation that talks about this explicitly?
Any direction on this would be helpful.
If you are using AWS SSL Certificates from Certificate Manager, renewal is automatically handled and changing the certificate from your application load balancer or CloudFront is not required.
Check this documentation for more details.
