I had imported a SSL certificate into AWS long time ago. It is currently installed on the ELB, and it is going to expire in 15 days. I am trying to get AWS to issue a new certificate but it is stuck waiting validation:
Currently Route53 is pointing to the ELB. If I enter "https://eyecloud.net.au" it works fine.
Now, I tried to create a CloudFront, so that I can redirect HTTP to HTTPS. But the imported SSL certificate does not show up:
I deleted the ELB, and the imported certificate becomes not in use, but it still doesn't show up on CloudFront.
There is no problem using a certificate with multiple endpoints, whether they're ELBs, ALBs, or Cloudfront distributions.
However, if you want to use an ACM cert for Cloudfront, the cert must be issued in us-east-1.
Note
To use an ACM Certificate with CloudFront, you must request or import the certificate in the US East (N. Virginia) region.

I had a case where I already had an SSL certificate selected, and when I clicked on the dropdown it only showed the selected one.
Turns out that Amazon doesn't like UX because it is not a normal dropdown it is a "searchable" dropdown. Meaning if you have a certificate selected, it will only show that specific certificate because it is also searching it in the dropdown.
Clicking on it and deleting the name reveals the rest of the certificates.
See below examples:
UX.
Where are my certificates?
Oh...
My problem was, that I got generated a 4096 bit certificate, but Cloud Front only allows for 2048 bit certificates
CloudFront [...] with ACM support a maximum of 2048-bit RSA certificates
I created my certificate with ZeroSSL and I didn't manage to create a 2048 bit one. To do that, I installed Ubuntu on my Windows machine (needed to install the Windows Subsystem for Linux in the 'Turn Windows features on or off' section) and used Certbot for Ubuntu with this command to create a 2048 bit certificate while using dns validation:
certbot -d yourdomain -d www.yourdomain --manual --preferred-challenges dns certonly
The 4096 bit certificate didn't show up, but the new 2048 bit certificate did, after deleting the contents of the drop-down menu, like stated by #Gopgop. You can see what kind of encryption rate your certificate has when importing the certificate into AWS Certificate Manager, on the review and import page, "Public key info". If you create a new certificate with ACM, that one automatically has a 2048 bit encryption and can be used right away in Cloud Front.
I have applied the same certificate to multiple endpoints or on multiple cloudfront distributions.
Also if you notice you cannot apply the cname to mutiple endpoints as well. You can use the cname it only in one place.
Only issue I have seen is your conversion from custom certificates to ACM certificate. There could be a bug with that. You might need to file a support ticket to resolve the issue.
Hope it helps.

I am trying to add SSL Certificate in ALB, but getting following error.
I have requested successful 1 ACM Certificate, but unfortunately that was wrongly configured, and this issue is repeating after deleted my first ACM Certificate. Does AWS not allow to create multiple ACM Certificates ?, I dint found edit option to change FQDN hence I have to delete old cert
What is probable root cause, I tried to connect support team unfortunately ticket is still open.
As per docs
ACM requires additional information to process this certificate request. This happens as a fraud-protection measure if your domain ranks within the Alexa top 1000 websites. To provide the required information, use the Support Center to contact AWS Support. If you don't have a support plan, post a new thread in the ACM Discussion Forum.
In my view [ only possible solution ]
All Amazon certificates for these domains will remain functional until expiration, but will not be renewable and no new certificates from these domains will be issued. The only workaround that would work in your scenario would be to obtain a certificate from a third party that can issue a certificate for your domain, and import the certificate into ACM
Contacting Support is recommended to resolve the issue as explained in this document. Also, it's not possible to change domain names when a certificate has been requested and you can create multiple certificates in ACM.
I am posting this here to help others facing this problem as I could not find any useful information on the web.
If you have mapped your ACM certificate to an end-point (EC2, ELB, EKS service.. whatever) You will need to enable
CertificateTransparencyLoggingPreference
Else you will get:
NET::ERR_CERTIFICATE_TRANSPARENCY_REQUIRED
Error in chrome. To do this via the aws-cli, the command is:
aws acm update-certificate-options --certificate-arn <ARN of ACM certificate> --options CertificateTransparencyLoggingPreference=ENABLED
I have provided the full response from AWS support as the answer, as this contains even more information.
This is Vivek from AWS Containers team. I will assist you on this
case.
From the case description, I understand that you requested an ACM
certificate and created ELB(service load balancer) behind which you
are running nginx pods in EKS cluster example-EKS-CLUSTER-dev.
When accessing the site https://test-aws.example.co/ from browser you
are getting error as below:
Error: NET::ERR_CERTIFICATE_TRANSPARENCY_REQUIRED
You would like to use a third party CA such as lets encrypt to issue
free SSL certificate for your domains. You do not want to move the
domain to Route53.
You wish to know how to to do this and achieve https.
Please let me know if my understanding is correct.
Regarding the error ERR_CERTIFICATE_TRANSPARENCY_REQUIRED, this error
is thrown by Chrome browser when it can not find CT(certificate
transparency) logs.
For Google Chrome to trust the certificate, all issued or imported
certificates must have the SCT information embedded in them.
By default ACM logs all new and renewed certificates. However, it
provides option to opt out from AWS API or CLI.
You may find more about this on link [1].
I checked the load balancer mapped to the domain “test-aws.example.co”.
It is mapped to ELB
abce6962e05794f36a23435db3f1837d-1755308045.eu-west-2.elb.amazonaws.com
which uses ACM certificate
arn:aws:acm:eu-west-2:150737547637:certificate/f932b11d-af17-4023-be41-045c6fcc5e86
I checked this certificate and found that the option
“CertificateTransparencyLoggingPreference” is disabled.
You may enable transparency on the certificate to fix the issue by
running following command:
aws acm update-certificate-options --certificate-arn --options
CertificateTransparencyLoggingPreference=ENABLED
Once the certificate is updated with
CertificateTransparencyLoggingPreference as enabled, the issue will
resolve i.e. you should not longer receive the error
NET::ERR_CERTIFICATE_TRANSPARENCY_REQUIRED when accessing the site
over https.
Regarding your other query, i.e. how to use a third party certificate
such as LetsEncrypt with ELB for https, you may obtain the desired
certificate(get it issued from desired CA) and import it in ACM or
IAM. Once the third party certificate is imported in ACM/IAM, it can
be associated with the https listener of ELB similar to how you
associate certificate issued by ACM(by using annotation
service.beta.kubernetes.io/aws-load-balancer-ssl-cert in service
definition yaml with value as the ARN of imported certificate).
Please find the steps to import certificate in ACM on link [2]. The
steps to import a certificate in IAM can be found on [3].
I'm creating a CloudFront distribution for an S3 bucket. I successfully created it and mapped the DNS. Now I want to use HTTPS for the DNS.
I created a cert via ACM. But the cert is not appearing in the CloudFront Custom SSL pge.
Any ideas why?
I was able to accomplish the task, however, this is not the answer to the question.
I pasted the certificate ARN to the Custom SSL field and updated the CloudFront distribution. By this way, I was able to add SSL to my custom domain. However, my certificate still not appears in the Drop down menu.
Pls verify whether the certificate is created in us-east-1 region. Cloud front can use certificates that are created in that specific region.
We are using cloudfront to serve images with a custom domain.
http://images.example.com/fubar.png
We want to be able to access them with SSL, eg https://images.example.com/fubar.png
We have a wildcard SSL certificate (issued from Godaddy) for *.example.com and I used the AWS Certificate Manager to upload the certificate, private key, and keychain. The upload appears to have been successful as *.example.com appears to be issued (according to the Certificate Manager).
How do I "apply" this wildcard SSL to images.example.com? If I visit CloudFront Distributions and edit the General settings to select Custom SSL Certificate I can see my *.example.com wildcard SSL. But when I try to click the Yes, Edit button I get the following error message:
com.amazonaws.services.cloudfront.model.InvalidViewerCertificateException: The specified SSL certificate doesn't exist, isn't in us-east-1 region, isn't valid, or doesn't include a valid certificate chain. (Service: AmazonCloudFront; Status Code: 400; Error Code: InvalidViewerCertificate; Request ID: ffffffff-ffff-ffff-ffff-ffffffffffff)
What steps do I need to take to allow me to apply this Wldcard SSL cert to my cloudfront images with custom DNS name?
Cannot say for sure, but typically with issues like this your certificate chain is incorrect. You’ll need to check the certificate authority’s instructions for creating the chain (e.g. what intermediate certificates does it need).
I got the same error, and finally found out it's the the maximum size of the public key in an SSL/TLS certificate issue.
AWS CloudFront only support 2048 bits, although Certificate Manager allows you to import 4096 bit keys.
Please refer to:
https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/cnames-and-https-size-of-public-key.html
Especially this one: step by step

I am creating a SSL certificate for my amazon S3 static website. I created a SSL certificate using Certificate Manager for my domain and its status is 'Issued'. I am creating a CloudFront Distribution, but the Custom SSL Certificate option is disabled.
Will it take some time (a day or more) before I can see my custom SSL certificate? Or am I doing something wrong?
Certificates that will be used with an Application Load Balancer (ELB/2.0) need to be created in ACM in the same region as the balancer.
Certificates that will be used with CloudFront always need to be created in us-east-1.
To use an ACM Certificate with Amazon CloudFront, you must request or import the certificate in the US East (N. Virginia) region. ACM Certificates in this region that are associated with a CloudFront distribution are distributed to all the geographic locations configured for that distribution.
– http://docs.aws.amazon.com/acm/latest/userguide/acm-regions.html
The reason for this is that CloudFront doesn't follow the regional boundary model in AWS. CloudFront edge locations are all over the globe, but are configured and managed out of us-east-1 -- think of it as CloudFront's home region. Once a distribution reaches the Deployed state, it is not operationally dependent on us-east-1, but during provisioning, everything originates from that region, so that's the only ACM region that CloudFront can access.
I was getting this exact behavior but with the certificated correctly imported at us-east-1 and figured out that the problem was the key size of my certificate (4096 bits).
AWS CloudFront only accept keys up to 2048 bits, as stated here: https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/cnames-and-https-requirements.html#https-requirements-size-of-public-key
Size of the Public Key
The length of the public key for a certificate depends on where you're storing it.
Importing a certificate into AWS Certificate Manager (ACM): public key length must be 1024 or 2048 bits. The limit for a certificate that you use with CloudFront is 2048 bits, even though ACM supports larger keys.
Uploading a certificate to the AWS Identity and Access Management (IAM) certificate store: maximum size of the public key is 2048 bits.
We recommend using 2048 bits.
When replacing a cert, make sure you clear out the name of the existing cert in the 'Custom SSL Certificate (example.com)' text box. If you leave it uncleared, other certs are not selectable.
Had thesame experience while trying to create a cloudFront distribution. I initially created the certificate in the us-west-2 region but the checkbox was greyed out. What resolved it was creating the certificate in the us-east-1 region. Checkbox immediately became selectable.
