title: Unable to curl on-prem domains with HTTPS from AWS
body: <p>We have an on-prem CA. All are able to resolve domain text.example.com(private domains) from on-prem. Now I have a requirement to connect those URL's from AWS. Established Site-to-site VPN from AWS to on-prem. Added DNS IP address in Route53 Resolver and able to ping on-prem domains but not with HTTPS. Getting below error:</p>
  <pre><code>curl: (60) SSL certificate problem: unable to get local issuer certificate
  More details here: https://curl.se/docs/sslcerts.html
  
  
  
  curl failed to verify the legitimacy of the server and therefore could not
  establish a secure connection to it. To learn more about this situation and
  how to fix it, please visit the web page mentioned above.

  <p>As I am able to resolve domain within VPC, I am looking response over HTTPS within VPC. Tried with AWS ACM, but no luck.</p>
  <p>Any pointers??</p>
