When generating a CSR for a wildcard TLS/SSL certificate you have to ensure the domain is in the correct format.
When you generate your CSR or enter the domain during the order process make sure you include the wildcard element. For example a wildcard certificate for Servertastic would be in the format *.servertastic.com
This means you have purchased a wildcard SSL certificate but your CSR does not contain a wildcard domain.
The wildcard SSL certificates issued by ServerTastic cover both *.yourdomain.com and yourdomain.com
Due to strict validation requirements set down by all Certificate Authorities wildcard EV certificates are not available from any provider.
This occurs when you are attempting to configure your order using a wildcard domain such as *.example.com but your order is not for a wildcard certificate.
