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 follow Document for Creating Content-Based Load Balancing: https://cloud.google.com/load-balancing/docs/https/content-based-example
I want to reach external address with https. I want load balancer to connect to VM with simple http.
Both VMs work as expected and are returning proper answet when reached by IP address. LB's settings seem fine. Both health checks are passing and Google SSL Certificate is ACTIVE.
However, when I try to reach Load Balancer's IP address or domain I get 502.
LB IP is 35.244.161.226 wciel.pl
Load Balancer's logs show statusDetails: "failed_to_connect_to_backend"
I attached screens of my Google Cloud Console.
Please advice.

I think there is a mismatch in back end service configuration. From the details of web-map-backend-service its seems like your service listening on port 80. However, when you have configured backend service you have configured it with port 443.
If you don't require secure communication between LB to VM, I would recommend followings:
Change backend protocol from HTTPS to HTTP
Edit backend Port numbers from 443 to 80
Save and update the configuration.
I have set up an instance reachable on http.
I have set up an instance group containing that instance.
I have set up Loadbalancing using an self signed ssl cert.
The external IP of the LB and the instance can be reached.
The forwarding of the request from the LB runs into an time out.
The config for Loadbalancing says "you have 0 instances without errors, you have 1 instance with errors."
I don't see any log entries in the apache logs coming from the lb frontend.
There is no http connection from Google addresses showing up.
Any ideas where to look for or hints to a good guide (not the rather good google docu)?
Yes. You can use Compute Engine HTTPS load balancer with HTTP backend services. Select HTTP as Backend services protocol. For health check, use HTTP health check. Add GCE firewall rules to open tcp:80 for 130.211.0.0/22 and tcp:443 for 0.0.0.0/0 source IP ranges.
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 a PHP app deployed on Elastic Beanstalk, currently with a single instance behind a load balancer and am attempting to enable SSL. The current configuration is as follows:
-I've uploaded my certs to IAM successfully
-On the EB Console Load Balancer config "Listener Port" is off, "Secure Listener Port" is "443", and "Protocol" is set to "HTTPS"
-In my Loadbalancer, accessed through the EC2 console, Load Balancer Port/Protocol 443/HTTPS and Instance Port/Protocol is 80/HTTP (the default HTTP/80 HTTP/80 listener is still there but i've tried removing it to no joy)
-My security groups for both the load balancer and the instance are configured the same: Inbound is allowing all connections from either security group, plus inbound http on 80 and https on 443 (source= 0.0.0.0/0)
When attempting to access the url https://myurl.com, I get 503 service unavailable (server at capacity). I suspect there is an issue with my security group configuration, but can't figure out what it is (have tried referring to this thread).
Any Ideas?
I just experienced this on my ElasticBeanstalk deployment and the reason was that my elastic load balancer had 0 healthy instances in service. There's different health check settings, one that checks over HTTP:80 and one that checks over TCP:80. I haven't investigated thoroughly but for some reason the HTTP:80 setting will result in my servers being marked as unhealthy, but TCP:80 will test correctly. If this comes up again I would suggest looking in there?
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.
