I bought a domain named studileih.de, then I deployed my Angular frontend on firebase: https://studileih-ceb70.web.app/ and redirected from my domain studileih.de to the firebase URL.
Then I deployed my Spring Boot backend to AWS Elastic Beanstalk on: http://studileih1.eu-central-1.elasticbeanstalk.com/
-> Problem: Since the frontend on firebase used https and the backend on AWS used http I got a Mixed content error. The frontend wasn't able to load any of the backend data.
So I tried to solve this by creating a SSL certificate for my backend in the AWS Certificate Manager (ACM) and adding this to my Elasting Beanstalk Load Balancer. This worked and I could now at least make a connection from my frontend to my backend.
But now I get this error whenever a request to my backend gets sent:
When I click on "Accept the Risk and Continue" once, it works fine and all my backend data gets loaded. But I can't ask my users to do that.
(You can try this out by following: https://studileih1.eu-central-1.elasticbeanstalk.com/products and clicking "Advanced" -> "Accept the Risk and Continue" (if you dare ^^)
after you've done that, click on studileih.de and it will now load with the backend data.)
I know the problem exists because when creating the SSL certificate, I entered studileih.de as the domain that the certificate is for. I think I have to create a SSL certificate for studileih1.eu-central-1.elasticbeanstalk.com instead.
But when I try to create a SSL certificate for studileih1.eu-central-1.elasticbeanstalk.com:
I get this error from ACM:
How do I create a SSL Certificate for the Elastic Beanstalk URL?
p.s. I also tried to issue a certificate for my firebase URL https://studileih-ceb70.web.app/ but this one already uses Https by default. Also I couldnt find out how to DNS/Email validate the ACM request in the firebase console. But I think I need a certificate for the Elastic Beanstalk backend at studileih1.eu-central-1.elasticbeanstalk.com, not for the firebase frontend, right?
p.p.s. I don't really need to use https, so a solution would be to make firebase use http instead of https, but I couldn't find anything on how to do that.
UPDATE:
I added a subdomain called api.studileih.de (the immediate access is blocked by spring security, as you're not logged in to my site, but you can test it with api.studileih.de/products, because this API is accessibly without login). Then I redirected that subdomain to my AWS Load Balancer as suggested by Mark B by adding a CNAME to the subdomain:
(it's not possible to change to english there, sorry)
this is my Load Balancer:
I tried to put the DNS-Name as A-Record into my subdomain, but it was only possible to enter a IP4 adress there, so I entered it as CNAME instead. I also tried to find out the IP Adress of the Load Balancer, but Load Balancer don't have a static IP Adress.
This approach with the subdomain and the CNAME unfortunately didn't work, so I'm still looking for a solution...
(Here's the menu for setting a A-Record. You can only enter IP Adresses there:)
I know the problem exists because when creating the SSL certificate, I
entered studileih.de as the domain that the certificate is for. I
think I have to create a SSL certificate for
studileih1.eu-central-1.elasticbeanstalk.com instead.
You can only create an SSL certificate for a domain you own. You need to point a subdoomain of studileih.de, like api.studileih.de, at the Elastic Beanstalk load balancer, and then attach an SSL certificate to that load balancer that matches that subdomain.

I want to have a subdomain (api.mysite.com) which makes calls to an EC2 classic load balancer (load-balancer-123456789.us-east-2.elb.amazonaws.com). Everything is hosted on AWS, to (theoretically) make it as straightforward as possible.
I created a domain and subdomain in AWS Route 53, as per the instructions here, and created an "A" record in the subdomain that links to my load balancer as an alias. That works fine, I can make calls to the load balancer through api.mysite.com, as long as I use HTTP.
But when I try to use HTTPS, I get ERR_SSL_PROTOCOL_ERROR. If I try to open the API in a browser, the security icon says that it's "not secure". I think the problem might be that the certificate is connected to the main domain (mysite.com) instead of the subdomain (api.mysite.com), but I can't figure out how to get it to resolve properly.
This SSL checking site shows the EC2 server itself (the one that the load balancer points to) and reports "Certificate not valid for domain name". It's an Ubuntu server, though I'm not sure if that should matter.
The SSL certificate needs to specify the subdomain as well as the main domain. The easiest way to do this is through AWS's Certificate Manager, by requesting a new certificate.
Make sure to specify each relevant domain and subdomain in the certificate (in this case, both mysite.com and api.mysite.com.)
After creating the certificate, go to the Load Balancer, open up the Listeners tab, and select the HTTPS port. Then, change the SSL certificate for that port to the certificate that includes the relevant subdomain. If you use AWS Certificate Manager, it can be selected from the dropdown menu.
I'm about to lose my mind trying to set this up. I have lost the whole day and can't seem to get near what I want to do.
I have a node js rest api uploaded trough elastic beanstalk, and I'm trying to setup a webpage to present the api, but for the live example to work the api needs to be accessed trough https. I've read the instructions for setting up the https for elastic beanstalk (and like everything on the AWS documentation it is a ridiculous maze). It has sent me trough several different AWS services.
What I basically got from it so far is that I need to set up a Load Balancer that will receive the connection trough https and forward the user to my instance. But I can't get it to work. I have a domain from freenom: bibliaparahumanos.tk, it is setup with an A alias to my EC2 IP, and it works with http, but if I try to access it trough https, I get "connection refused". If I use my normal Elastic Beanstalk url (http://apibibliahumana-env.eba-3nbmrphf.us-east-2.elasticbeanstalk.com/) with https it works, but I get a warning that the connection is not secure due to the domain on the certificate being different from the domain I'm accessing (which I understand, since the domain in the certificate is for my freenom domain).
I have the Load Balancer Listener set up with:
Protocol: https
Port: 443
Default action: forward to target group
(I have tried the target group with both http and https and the problem remains).
My certificate is from AWS Certificate Manager.
I have also seem this other tutorial but it confused me more. It adds some steps for configuring stuff on the app bundle, but I don't understand if it's required or an alternate way. I have tried setting that up, but it asks me to add the certificate's public key, which I can't figure out how to find.
I would suggest adding a CNAME record to your DNS towards apibibliahumana-env.eba-3nbmrphf.us-east-2.elasticbeanstalk.com.
A big advantage of using elastic beanstalk is that you can do blue/green deployments; as you will instead add the app URL to your DNS you can build an entire new environment in elastic beanstalk, test/wait until its stable and swap the app urls; which results in deployments without any downtime.

I have a backend service i'm running in Fargate. I need this service to have an SSL cert on its load balancer so that it can talk to other HTTPS services. I've created the load balancer and it gives me an AWS domain (my-cool-app.us-east-1.elb.amazonaws.com).
Now, when I try to request a certificate through acm, it fails and says "Additional verification required". So i'm not sure if it's possible to add an SSL cert to this load balancer without registering a custom domain?
Also, this is a Django app and I haven't done anything other than keep it as runserver which I know isn't good for production but I just need to start by making it work as a dev environment. Do I need to change the way Django runs in order for SSL to work? Or is the load balancer sufficient?
To use an SSL for a domain you need to have control over that domain. For the AWS managed certificate service (ACM) you can verify through either DNS validation or email validation both of which you must essentially have domain control to validate.
As you're trying to use ACM for a AWS owned domain, someone from AWS would need to approve the SSL (which they won't).
Regarding your second point what you're describing is SSL offloading, in which the load balancer will serve HTTPS and then terminate encryption in transit. It will then forward the request to the Fargate container using the protocol and port defined in the target group.
The only thing you want to consider is how you display to the user, for example ensure that all CSS, JS ans links on your site are HTTPS. You can detect whether the incoming request used HTTPS at the load balancer by inspecting the X-Forwarded-Proto header in your application.
Background
I am trying to deploy a dummy application with React frontend and Django backend interacting via REST api. I have done the following:
Use a S3 bucket to host static website and deploy my react code to it
Put Cloudfront for S3 bucket - set up certificate and changed my domain name (from GoDaddy) to link to this address
Kicked off Elastic Beanstalk environment following the python environment tutorial of AWS
Set up Postgres RDS and linked the Django server with it
So now I can do the following
Access my frontend using https via my domain name (https://www.example.com)
Access django admin site using the path of elastic beanstalk and update items
i.e. each component is up and running
Problem
I am having trouble with:
Making a secure REST API call from the static page to Elastic Beanstalk environment. Before I set up certificates I could easily make REST API calls.
The guides I can find usually involve putting a domain name for Elastic Beanstalk, which I imagine does not apply to my case (or does it?)
I tried to follow this faq and updated configuration in load balancer that accepts 443 https and redirects to 80 http. But I am using same certificate as from CloudFront, which does not sound right to me.
Would appreciate help with
how to solve the above ssl connection issue
or is there a better architecture for what I'm trying to achieve here?
According to Request a certificate in ACM for Elastic Beanstalk backend, it sounds like I have to use a subdomain and request a certificate for that subdomain, and use Cloud 53 to direct requests to that subdomain to Elastic Beanstalk environment. Would that be the case?
Thank you in advance!
By default EB url will HTTP only. To use HTTPS you need to deploy SSL certificate on your ALB.
In order to do that you need a custom domain, because you can only associated an SSL certificates with domains that you control. Thus, normally you would get a domain (you seem to already have one from godaday). So in this case you can setup a subdomain (e.g. api.my-domian.com) on godady. Then you can use AWS ACM to register a free public SSL certificate for api.my-domian.com.
Once the certificate is verified, using either DNS (easier) or email technique, you deploy it on your ALB using HTTPs listener. Obviously you will need to point api.my-domian.com to the EB's https url. You can also redirect on your ALB http traffic from port 80 to 443 to always use https.
Then in your front-end application you only use https://api.my-domian.com, not the original EB url.
There can be also CORS issues alongside this, so have to be vary of them as well.
My iOS software platform runs on AWS Elastic Beanstalk and has a URL we'll call "something.elasticbeanstalk.com". I have a website we'll call "website.com" I purchased and operate the DNS records for through Namecheap. I need to make the URL my iOS client apps use to connect to the server HTTPS since Apple is requiring this soon due to App Transport Security.
WHAT I THINK I'M SUPPOSED TO DO
What I think I'm supposed to do is, create an SSL certificate for "website.com" and apply that SSL certificate to the AWS EB load balancer. Then I need to create a subdomain for "website.com" that redirects traffic to "something.elasticbeanstalk.com". Client apps connect to the subdomain of "website.com" which is now HTTPS and redirects to "something.elsastic.beanstalk.com". Is that correct?
WHAT I'VE DONE SO FAR
So far, I created a SSL certificate for "website.com" using AWS Certificate Manager. For this I had to verify my email address associated with "website.com". I then applied that SSL certificate to my environment's load balancer int the AWS Management Console. After that, I went into Namecheap and followed this guide in the 'Domain Name & AWS 53 Management' section to do it.
I read in this article that I needed to create an alias and/or set up Nameservers in AWS Route53. I tried doing that but don't know what I'm doing and it seems to conflict with the Medium article I linked above that I followed telling me to change the CNAME record for the URL and the Redirect URL record for "website.com".
QUESTION
What do I do from here?
SITUATION
-I have a Parse Server on Elastic Beanstalk with URL “something.elasticbeanstalk.com”
-I have a domain with Namecheap called “website.com”
WHAT I NEEDED
I needed to make my client app connect to an HTTPS address since Apple is requiring it shortly with App Transport Security. Since I couldn’t get an SSL certificate using AWS certificate manager for “something.elasticbeanstalk.com”, I created one for “website.com”. I then needed to have my client app connect to the HTTPS “website.com” which would forward it over to “something.elasticbeanstalk.com”. This satisfied the HTTPS requirements of Apple.
HOW TO DO IT
Make an SSL certificate for “website.com” using AWS Certificate Manager. You will need to confirm the domain via a confirmation email to the administrator for it.
Apple the SSL certificate for “website.com” to the AWS EB Load Balancer. Go to your AWS EB Console, click "configuration", click "Load Balancing" under the "Network Tier" category. Now under the first category which is "Load Balancer", select the SSL record you made and apply it in the "SSL certificate ID" section.
Set a CNAME record for “website.com” with a host of whatever subdomain of “website.com” you want. I chose “data” as my host value and subdomain (so my subdomain is “data.website.com”). Set the value of the CNAME record to “something.elasticbeanstalk.com”. Wait for it to propagate. It’s usually pretty fast but not always.
(I’m unsure if this particular step is proper but it worked for me) Set the serverURL of Parse-Server to “https://something.elasticbeanstalk.com” and the publicServerURL to “https://data.something.com”
In the Parse “initializeWithConfiguration” method in your client app that enables the app to connect to the server, change the server URL to “https://data.something.com/parse”. NOTE: include the “/parse” which is the MOUNT PATH of the parse-server. This value MAY BE DIFFERENT for you depending on how you set it but I set it to “/parse” since that’s what I saw in the Parse-Server docs.
NOTES
-I deleted all Route53 records since they are irrelevant here since “something.com” DNS services are controlled by Namecheap.
-A Redirect URL record in Namecheap is unnecessary
