I have added a alias domain (vhost) abcd.com letsencrypt certificate working fine for this domain. Then i added 1.abcd.com alias domain (vhost) too but letsencrypt can't be enabled for this alias domain. Before i had a alias domain (vhost) 2.abcd.com letsencrypt certificate working fine on this domain but i have removed the domaind and added again now it's not working too. How can i fix this issue?
