For react build deployment - put buli in (/var/www/html) folder
PORT 80 - is for http ip access link (comment it out in httpd.conf file)
PORT 443 is for HTTPS ip access link 

For redirection reload "404 error" issues-

1) Change httpd.conf file in (/etc/httpd/conf)and in .htaccess build folder (/var/www/html). 

2) Note: This two files should contain the same below code i.e.-> 

RewriteEngine On
RewriteBase / 
RewriteCond %{REQUEST_FILENAME} !-f 
RewriteRule ^ index.html [QSA,L]

3) Note:  in document root "/var/www/html" change AllowOverride to All.

After this re-run the Apache server command - apachectl restart
