Conclusion:

Webmin:

Open browser and go to https://192.168.1.11:10000 and login as 'root'.

If you have DNS configured, then https://tyrion:10000 will also work in the browser. And if you are on the same machine, then https://localhost:10000 will also work in the browser.

Usermin: 

Open browser and go to https://192.168.1.11:20000 and login as any user except root because root user has been disabled for usermin.


If you have DNS configured, then https://tyrion:20000 will also work in the browser. And if you are on the same machine, then https://localhost:20000 will also work in the browser.
