Angular 8 app hosted in Nginx server gets 404 page when refreshed

Angular 8 app hosted in Nginx server gets 404 page when refreshed

This is because of NGINX not able to find the index.html of Angular app

modify the site-available/default config file of nginx like below 

try_files $uri $uri/ /index.html;

server {
        listen 80;
        listen [::]:80;

        root /var/www/example.com/html;

    index index.html index.htm index.nginx-debian.html;

        server_name example.com www.example.com;

        location / {
            try_files $uri $uri/ /index.html;
         }
}
