please help me or a hint to solve this ..........how to create certificate for domain that have *.domain.com alias subdomain

NOT possible! You cannot use wildcards when applying for a domain at LetsEncrypt. However .. what does work is setting up a Flex SSL wildcard for A or CNAME records and then have https://www.cloudflare.com manage your DNS.

But the whole purpose of Full SSL is security. Wildcards ain't about security.
