Website is offline | Error 522 Connection Time Out

Hi!

    Yesterday when I tried to open my website http://freeiweb.com/ and cpanel http://freeiweb.com/cpanel/ it's showing "Website is offline | Error 522 Connection time out". Can you please help me to figur out this problem.

   Before the few days ago I've added a "*" subdomain to make my website a multisite. That time and even after that my website was working very well. Now I'm confused that this is the problem or something else, because I'm not able to open cpanel and don't have other link to open cpanel. So please guys help me to solve this problem.

Thanks & Regards
