CWP: How to add Lets Encrypt SSL certificate to Webmin

By default, Webmin uses a self-signed SSL certificate so your web browser will warn you that the connection is not secure. You can accept the self-signed SSL certificate and proceed to the log in screen. Let's replace it with a valid certificate from Let's Encrypt. We have already generated Lets Encrypt SSL certificate for our Server FQDN using certbot. Please check the Let's Encrypt section for How to install Let's Encrypt for Server FQDN?  Click Here Open the configuration file and add the following : # systemctl stop webmin # vi /etc/webmin/miniserv.conf ssl=1 server=MiniServ/1.900 userfile=/etc/webmin/miniserv.users keyfile=/etc/letsencrypt/live/ certfile=/etc/letsencrypt/live/ For CWP: keyfile=/etc/pki/tls/private/hostname.key certfile=/etc/pki/tls/certs/hostname.bundle # This will redirect from http to https ssl_redirect=1 Restart the Webmin Service: # systemctl restart webmin # systemctl

CWP: Getting error "pam_unix(webmin:auth): authentication failure" on Latest Webmin 1.9 on CentOS 7.6 [Fixed]
