I have a web app in Azure. I have requested wildcard ssl certificate for *.blog.mydomain.com. I was going to use it on all blog subdomains as well as on blog.mydomain.com. However when I try to bind it on blog.mydomain.com it doesn't accept it. What could be the reason?
You need to specify both subject names blog.mydomain.com and *. blog.mydomain.com in the certificate's SAN.
