My site is loading default epizy.com site instead of my index.php file which is in htdocs folder

My domain is http://poudelmadhav.epizy.com/
When I upload my php files to htdocs directory, it is not loading index.php file of htdocs. It is showing the default directory of epizy.
When I want to go to my desired site i have to manually type it. Example: http://poudelmadhav.epizy.com/index.php
I want my example as root directory i.e it should load http://poudelmadhav.epizy.com/index.php when I go to root directory.
How can I do this?

It's working fine here.
It could be because of your browser cached the default index page. Try clearing your browser cache.

Thank you. Now it is working.
