After installing GRAV in my VPS I receive 404 Error

I just installed GRAV in a VPS Centos v7 (KVM)
After launching GRAV I see 404 error in home but not in typography; in typograpphy work well.

I Edited .htaccess and Uncommented RewriteBase and Changed to / and to /home/vpsserver/public_html/mydomain.com (is where is located grav) and neither worked

Please advise what to do

Thanks
