Site not opening

Hey, WordPress volunteers
I occurred a serious problem with my site. Actually I am hosting my account for free on infinityfree. And I follow all the instructions to add my custom domain in it, which was successfully done. But when I install WordPress in the Cpanel and use my domain in it. The site doesn’t open.
Kidly help me out.
Thank you.
