React/Angular Application showing 404 error on refresh

On Apache server, React Application works fine, but if you refresh a page, it shows 404 error. This is because the application use BrowserRouter. To fix the error, create a .htaccess file with following content

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

Put this on the folder where your application index.html is or in Apache Virtual Host entry.
