Background:
I had 1 instance created for EC2
I had my domain pointing to this instance
I had SSL installed for this instance (things were running great)
Furthermore:
I opted to create a second instance (using custom AMI from first instance)
I create a load balancer (things were working great -- from what i can tell...)
Question:
Why do I need to install the SSL certificate on the load balancer when it seems to have already been working?
I would presume when you say load balancer, you are refering to AWS ELB. If this is no the case, then disregard my answer.
Well the Best practice is to install SSL certs on load balancer and do the SSL termination there. Let the load balacner do SSL encryption/decryption so that your web server can do what they do the BEST...serving hte web pages.
Why do I need to install the SSL certificate on the load balancer
Now, technically You set is fine and you don't have to install SSL on load balancer. But then you have to use TCP Load Balancing feature of AWS ELB where in ELB will simply accespt traffic on 443 and will forward it to Web servers on 443. And then let your web servers do the SSL work.
I think this what you are looking for.

I have a node js app deployed onto EC2 instance running on port 300 and it is exposed to internet via port 80 & 443 via http load balancers.
My security group allows inbound rules on 80 & 443. I have created SSL certificates with ACM for a domain created on GoDaddy (domain name:- www.abcd-example.com).
For CNAME I added these values, Host(Name): _57xxxxxxxxxxxxxxx5d, Points to(value): _68xxxxxxxxxxx67.bxxxxxxxxxxxj.acm-validations.aws.
My ACM certificate was issued and I had loaded these certificate on to load balancer. Now when I try to access the load balancer with https://, I am getting this error : NET::ERR_CERT_COMMON_NAME_INVALID.
I am not sure why this is happening as I had followed all the steps mentioned in AWS docs to dot. Can anyone help me out in this?
I have the following infrastructure for my artifactory web server
Artifactory Server - myMainartifactory.myCompany.com
load balancer - myLoadbalancer01.myCompany.com
load balancer - myLoadBlancer02.myCompany.com
The SSL certificate is purchased for the domain myMainArtifactory.myCompany.com that both load balancers serve.From some posts including this one, I was under the impression that I could use the same private key and certificate for the load balancers.
But when I try to ping the docker registry it says that the certificate is for myMainArtifactory.mycompany.com domain.How does this work?
I am trying to configure my website to have a secure connection (https://) via Amazon's EC2, ELB, and Route 53.
I am running a t2.micro instance (no Elastic IP or anything). My Elastic Load Balancer has the SSL certificate attached. My SecurityGroup allows for https connections through port 443. I'm not sure what I'm doing wrong here.
All of my configurations are below. Any help is appreciated because, as it stands, I can't access my website at all.
Thank you in advance!
EC2 - - -
Load Balancer - - -
Route 53 - - -
Step 1: Hit the EC2 instance directly and verify that the health check URL responds with an HTTP 200 status code. If not, then get that working first.
You aren't clear about your security group configuration. You should have a security group on your load balancer that allows HTTP and HTTPS connections. Then you should have a security group on your EC2 instance that allows HTTP (port 80) connections from the load balancer's group.
The issue is obviously the failing health check on the load balancer at this point, so no need to look at Route 53 settings right now. You need to concentrate on getting the communication working between the EC2 instance and the load balancer to get that health check to start working. Until then the load balancer won't accept any traffic because it doesn't have instances it considers healthy that it can forward traffic to.
I have a load balancer in front on an ec2-Classic instance. I have checked that the load balancer is working properly by directly linking to the DNS Name value that is listed in the Description tab for my load balancer. This gives me the main page of the webpage that lies on the EC2 instance. Thus my load balancer is working. My load balancer and my EC2 instance are in the same avalibility zone.
My load balancer has set up an SSL certificate and I have two listeners setup to forward http (port 80) and https (port 443) to instance port 80 as http. My EC2 instance has a security group set to accept http and https with protocol TCP on ports 80 and 443 respectively. Although my understanding is that only the port 80 would be useful, right? The data for the certificate are in the pem format. I have addded to my instance security group a custom TCP on Port Range 0 - 65535 for amazon-elb/amazon-elb-sg. This did nothing.
I can access my site using http just fine. If I try to access using https then I get Error code: ERR_CONNECTION_REFUSED on Chrome and Unable to Connect on Firefox.
I have checked similar posts for this question and nothing seems to help.
Any help or ideas would be greatly appreciated. Thanks
Have you made sure that the ELB is in a security group that allows https on port 443?
I had a similar problem with both classic and advanced load balancer. The thing that was missing for me is that the https to http translation stuff only workers AFTER you make an A record in the DNS for the domain your SSL is on ALIASED to the load balancer you just created. Once I did that all was well through that new A record DNS. Your instance doesn't need to accept port 443 and your LB definitely should not be forwarding over 443.
Hopefully it is something straightforward like this for you as well.
Wait, what SSL certificate in PEM format? I used an Amazon SSL certificate I just got from the dropdown. Are you sure you used an SSL certificate?
In your description I see that maybe you are not following Step 6 from Amazon's "Elastic Load Balancing in Amazon EC2-Classic ->Create HTTPS/SSL Load Balancer
Using the AWS Management Console -> Configure Listeners" guide.
There, it says that you should configure "HTTPS (...) in the Load Balancer Protocol [and] HTTPS (Secure HTTP) (...) in the Instance Protocol box.", whereas in your configuration you are forwarding ELB's 443 to port 80 in the instance.
For further reference, this is the guide that I'm talking about DEAD LINKhttp://docs.aws.amazon.com/ElasticLoadBalancing/latest/DeveloperGuide/configure-https-listener.htmlDEAD LINK
Also, check if your SSL certificate is well built according to the rules specified here: http://docs.aws.amazon.com/ElasticLoadBalancing/latest/DeveloperGuide/ssl-server-cert.html
I have an EC2 instance with Apache and Tomcat servers. And I want to add SSL certificates for https access. Since I am new to server technologies, can anybody help me on this? Where do I configure SSL certificates?
Setup a Elastic Load Balancer (ELB) in front of your EC2 instance you can upload ssl certs to these
