Home › Forums › Email Marketing General Support – Open › Webmin Server: I face error when Applying Let’s Encrypt SSL Certificate!
After I added a virtual server to my Webmin server, and now I am trying to issue an Free Let’s Encrypt SSL certificate, the operation failed and shows an error like this:
request failed: Web-based validation failed: Failed to request certificate…
request failed: DNS- validation failed: Failed to request certificate…
How can solve this issue?
This problem usually happens if you are trying to issue a certificate for a domain or subdomain that is not pointed to your VPS Ip address where webmin is installed.
So either point all domains and subdomains that you are trying to secure, or set specific domains in the box (in the SSL page)
Also trying installing Certbot manually by running the following command:
apt-get install certbot
Then try issuing the certificate again from the interface.
