SSL certificates not working (AWS Route 53)

Question

Because they expired before, I just updated the certificates of a website with DNS in Amazon Route 53 using this tutorial. For the new certificate I listed a domain (somedomain.com) and several subdomains (a.somedomain.com , b.somedomain.com).

All the steps described in the tutorial worked and checking on ACM the certificate is already listed as issued. I used the Create record in Route 53 tool in ACS to write the records in Route 53.

In Route 53's dashboard, the CNAMEs for the new certificate are listed.

However, in ACS, the certificate is listed as not used and, more importantly, my website shows up as having invalid certificates when accessed from a browser.

Am I missing any step here to update the certificate?

Is there something else needed to make the certificate renewal eligible?

Any help would be very appreciated.

Answer 1

ACM can be used with CloudFront/API gateway or ELB/ALB. just issuing a ACM certificate won't do anything, where is your website pointing ? Is it on Load balancer or CloudFront ? You need to use this new ACM certificate there. What certificate and error do you see when you access your website (e.g: hostname mismatch , cert expired)?
