Webmin – This web server is running in SSL mode. Try the URL instead.

I saw the above error while trying to access Webmin control panel in my web browser after webmin installation. Error shows that you have you have accessed webmin control panel URL without https in front. Web server is running in SSL mode so you must try using https instead of http. Try the URL “https://serverhostname:10000” OR “https://serverIP:10000” instead and check whether you’re getting the same error.

Access Webmin in your web browser using any of the below URL :

https://serverhostname:10000
OR
https://serverIP:10000

“serverhostname” should be replaced with actual hostname of the server. “ServerIP” should be replaced with IP address of your webmin server. When you access webmin with ‘https’ the browser will show certificate warning if SSL is not installed for your server hostname. Accept the server self signed certificate and proceed. It is better to access webmin using https instead of http because https is secure. Do the below steps if you want to disable SSL for webmin control panel.

1. Log into your Linux Server via SSH as root.

2. Take a backup of the file /etc/webmin/miniserv.conf

3. Edit the file /etc/webmin/miniserv.conf using vi editor

4. Change the line “ssl=1” to “ssl=0” (disabled)

5. Save the changes and exit. Now SSL is disabled for webmin.
