Answer 1

Try to use: http://nginx.org/en/docs/http/ngx_http_core_module.html#try_files

location ^~ /root {
    root /var/www/example.com;
    index index.html index.htm;
}
location ^~ /root/react_app(or panel) {
    root /var/www/example.com;
    index index.html index.htm;
    try_files $uri $uri/ /root/react_app/index.html;
}
