Question posted in 
I have been using the WP AWS S3 Offsite-upload plugin for a while now and recently it has asked me to create a url for my site as a subdomain and use that to point to my cloudfront.
so, I changed my DNS records to add a CNAME
sub.mydomain.com > somestring.cloudfront.net
When I went to any files sub.mydomain.com/wp-content/wp-uploads/2018/10/image1.jpg I get a ‘not secure’ alert.
After a google I this link on AWS: https://docs.aws.amazon.com/acm/latest/userguide/gs-acm-validate-dns.html
Using the steps there I went to the AWS Certificate Manager and generated a certificate for:
images.mydomain.com
and then downloaded the CNAME CSV file. I then added that CNAME to my DNS Zone editer on my CPanel and waited 24 hours.
Still I am getting a ‘not secure’ message.
In the AWS console the certificate says issued but not in use.
How do I get my subdomain images.subdomain.co.uk to point to my cloudfront installation?
I feel like it shouldn’t be this difficult so apologies if i’m being a noob

To resolve you have to use let’s encrypt so you get ssl issued and integrated perfect.for that please follow these steps : https://docs.bitnami.com/aws/how-to/generate-install-lets-encrypt-ssl/
If you are using AWS Route 53, to point your subdomain ‘images.subdomain.co.uk’ to CloudFront distribution, you need to create an Alias record set in your Hosted Zone. Select Alias: ‘Yes’ radio button while creating the record set and you should be able to see your CloudFront distribution in the drop down if it is in Deployed state.
