Homepage cannot be found

Visiting your domain name redirects to domain.com/index.html and that’s where your issue is – WordPress doesn’t know what index.html is and throws 404 error. The redirection might be caused by many things, hard to tell just by visiting your homepage. Are you sure that you’ve setup the WordPress URL and Home URL settings correctly? How about your .htaccess file? Maybe that’s coming from your server’s setup?
