Can't Generating CSR wildcard

[siamth]

when I generated csr with wildcard *.domain.com and submit, It's nothing to response



if I use full sub domain, it's generated



I need to use wildcard *.domain.com how to fix it

I think it's not possible to create a wildcard certificate.

You need to create a certificate for all the subdomains you need, specifying each one.

Wildcard certificate is only available from certifying companies, such as GlobalSign for example.
