Q:

AWS SES certificate verify failed

I have set up SES successfully on one AWS instance. Now I am trying to use it on a second (not cloned) instance and when I run any of the SES scripts, I get an error:
ses-get-stats.pl -k aws-credentials -q

I get:

Can't connect to email.us-east-1.amazonaws.com:443 (certificate verify failed)  LWP::Protocol::https::Socket: SSL connect attempt failed with unknown  errorerror:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed at /usr/local/share/perl/5.8.8/LWP/Protocol/http.pm line 51.

Getting the Perl stuff working was a challenge and it is possible I did it differently on the instance. Any place I should be looking to fix this?
When I run:
openssl s_client -CAfile .../cacert.pem -connect email.us-east-1.amazonaws.com:443 < /dev/null

I get:

This is the same response as on the instance where ses-get-stats.pl works.
After creating a certificate file as suggested by daxim, running:
openssl s_client -CAfile test.cer -connect email.us-east-1.amazonaws.com:443 < /dev/null

followed by additional information including the certificate.

A:

For some reason, your OpenSSL does not get the intermediate certificate. (Outdated software?)
Install the intermediate certificate with the subject hash 0xeb99629b, available at https://knowledge.verisign.com/support/ssl-certificates-support/index?page=content&actp=CROSSLINK&id=AR1513.
You can use it with the -CAfile parameter in OpenSSL tools and with the environment variable HTTPS_CA_FILE for the Perl HTTPS stack. To use it system-wide, place it in the appropriate ca-certificates directory, e.g. /etc/ssl/certs, and c_rehash the directory.
