**PLEASE NOTE**: if the web browser didn’t open the Webmin, there are no worries that are because it’s unsecured access, it’s opened up there because I had made an exception for it.

Add valid certificate for your Webmin by “Let’s Encrypt”

Webmin is configured to use “HTTPS”, but it uses a self-signed, untrusted certificate, Let’s replace it with a valid certificate from “Let’s Encrypt”.

1. Before we install the certificate we need to identify a hostname for Webmin, click on System Host name on webmin after you logged.

2. Set your Webmin hostname, as it shown below, and click “Save” after that.

3. After you had set your Webmin hostname, click on “Webmin Configuration”.

4. select from the icons that it will show to you “SSL Encryption”.

5. From the tabs, click on “Let’s Encrypt” tab, and write your Webmin hostname, as for “Website root directory for validation file”, select “Other Directory” and write “/var/www/html”.

6. Click “Request Certificate”, After a few seconds, you will see a confirmation screen.

7. To use the certificate you should restart your “Webmin” server, from “Webmin Configuration” tab, scroll down and click on “Restart Webmin”.
