Few months ago, I had faced this error while connecting to Webmin just after completing the installation. I had searched a lot and finally found one solution for this. Here I’m sharing this information for one who are facing this SSL problem with Webmin…

Webmin is one of the most commonly using Web Hosting control panels. This is an open source control panel which works on port 10000. Miniserv is the name of the web server application which handles the Webmin Web application. By default, Miniserv uses SSL for HTTP connections. This default setting cause some warning on the browser while accessing Webmin panel.
