what genuine process for generate new certificate for my wildcard subdomain
Wildcard certificates require that your domain is validated using DNS validation instead of using HTTP. To use DNS validation your ACME client (the software that is ordering the certificate) needs to be able to talk to your DNS provider an automatically update a TXT record.
Different ACME clients support different DNS providers so it depends which ACME client you are using to get your certificate and who your DNS provider is (e.g. do they have an API and is it supported by your ACME client).
