article.example.com
shop.example.com
mail.example.com

Wildcard SSL Certificate Limitations
Wildcard SSL Support only on First level domains of sub-domains. Like example – if wildcard issues for *.example.com so it supports only on blog.example.com, article.example.com, shop.example.com,
it doesn’t support on second level of sub-domains like abc.blog.exmple.com, pqr.blog.example.com.
If you want to secure multi-levels sub-domains so wildcard SSL certificate is not good options, you must go with Multi-domain wildcard SSL certificate that is also called SAN SSL certificate.
