Sometimes Webmin becomes inaccessible and we have to restart it. When you do this, it will work normally again.
To do this, just run the following command in SHELL:
/etc/init.d/webmin restart
After using the above command, you will see the following message:
Stopping Webmin server in /usr/share/webmin
Starting Webmin server in /usr/share/webmin
Now Webmin will work normally again!
