I am trying to generate an SSL certificate for a subdomain that was purchased using Wordpress. Both the domain and subdomain were purchased from Wordpress. For the subdomain created using Wordpress, I have created a A record with IP pointing to some external server. Now I want to generate a SSL certificate for this subdomain. How can I do this?
Here is what I tried using sudo certbot certonly --webroot command but gives the following errors.
What is it that I am missing?
