I have added wildcard subdomain in to cpanel using *.
Now my subdomain is creating automatically with SSL without wild card SSL. but problem is this when Vising domain directly xyz.com then its working fine if we add www.xyz.com then error comes. please refer link for error. ( Capture — ImgBB )
Is it actially just www.xyz.com or is it www.somethingelse.xyz.com?
If it;s the latter then the Cloudflare universal certificates cover example.com and *.example.com.
This means that it covers any subdomain one level above the domain you signed up with. It will cover www.example.com and subdomain.example.com, as these are one level above the root domain, example.com. The certificate will not cover www.subdomain.example.com or a.b.example.com, however, as these subdomains are too deep.
