Import AWS SSL Certificate Manager - Cannot Import Multiple Certificates

Question

I have an EV certificate for several subdomains for my website. List of allowed domains:

• cdn.subdomain.mydomain.com
• subdomain-staging.mydomain.com
• subdomain.mydomain.com

I want to use Cloudfront CDN with custom CNAME as cdn.subdomain.mydomain.comwell as EV ssl certificate. But whenever I try to import it in AWS Certificate Manager, I get the following error.

Can anybody help me?

My certificate is similar to

-----BEGIN CERTIFICATE-----
//CONTENT Intermediate CA Bundle
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
//CONTENT
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
//CONTENT
-----END CERTIFICATE-----

Answer 1

Divide the file into 3 files line by line -----BEGIN/END CERTIFICATE-----. Each file should look like this:

-----BEGIN CERTIFICATE-----
XXX a lot of base64 data here XXX
-----END CERTIFICATE-----

For each file use:

openssl x509 -in mycert.crt -text -noout
