Users are unable to signup for a site on my wpmultisite install


When I try to click on register, it takes me to which says page can not be displayed

however another domain on the same hosting space with the same dns settings does work find

Can someone please advise what might be going on ?

Currently I am using wp 3.22 on both of the installs and they are installed like /freewebsitedesigningindia/

and /bestreviewsites/ respectively.
