Hello.
When I try to connect to my subdomain using Virtualmin/Webmin, I receive an error notification that the date of the “Let’s Encrypt” SSL Certificate which was already activated and very operational for the Virtual Server (erp.mydomain.com), has expired which blocks direct access to the subdomain at the level of the various web browsers and considers this subdomain as a link which could be dangerous because it is not secure:
So, when I try to manually renew the SSL Certificate whose date has expired, I get the following error:
Requesting a certificate for erp.mydomain.com from Let's Encrypt ..
.. request failed : Web-based validation failed :

1 - How to correct this problem of updating the SSL Certificate (Let’s Encrypt) on my “erp.mydomain.com” subdomain (whose domain name “mydomain.com” is registered with “Namecheap” and the Server Web is a Droplet from “DigitalOcean”) knowing that this certificate was activated and working very well but all of a sudden it doesn’t work anymore???
2 - Is there an effective method to configure the automatic activation or update of the SSL Certificate when it expires ???
Thank you please help me.
