While the Subject CN is sv-issa.net there is another section of the certificate that your tool is not honoring:
openssl x509 -in sv-issa.net.crt -noout -text
...
Issuer: C=US, ST=Arizona, L=Scottsdale, O=GoDaddy.com, Inc., OU=http://certs.godaddy.com/repository/, CN=Go Daddy Secure Certificate Authority - G2
Validity
Not Before: Apr 30 00:17:38 2016 GMT

X509v3 Subject Alternative Name:
DNS:sv-issa.net, DNS:www.sv-issa.net, DNS:sv-issa.com, DNS:cornerstonesoftrust.net, DNS:sv-issa.org, DNS:cornerstonesoftrust.com
. This is not a certificate problem as just about every other browser and command line client supports this without error.
Since this is a multi-tenant hosting platform, I do not have control over the SSL certificate.
