The main hurdle to get over with wildcards is that you need to be able to automate DNS TXT record changes to your domain. Does your DNS host ( provide an API of some kind for updating records?

If not, you will probably be better off just using a non-wildcard certificate that has your main domain and subdomain on it

You can read about how to use Certbot to get wildcards here, if you are still interested: Getting wildcard certificates with Certbot
