Alias domain can not issue ssl,it show

I issued ssl after create alias domain,and message “Operation Successfull.” give me.

but when go uri ‘xxx.phpna.com’,can not open url,chrome said it is not safe.
howerver,I created after i created site,and go to “manage>ssl” to create ssl for site “phpna.com”,both domain “phpna.com” and “www.phpna.com” will work fine with ssl.
what’s wrong? what cloud i do to solve alias domain’s ssl problem? or its a bug?

the problem like this

yes, because it doesn’t issue wildcard domain , also one vhost can only comes with 1 cert, i think

Don’t use wildcards yet.
