@React-Vishnu you are trying to run [http-webnode](https://github.com/sthnaqvi/http-webnode) with -S, -S is used to enable https, please put key.pem and cert.pem files in the project root directory or you can pass those paths within arguments use -C or --cert for SSL cert file path and -K or --key for SSL key file path.

If you don't want to use https then remove -S and start the app on http with http-webnode ./app -a localhost -p 8000 -c-1

Hi @sthnaqvi thank you for your response . And i tried with ssl certificate path as you mentioned and without using -S but all shows the same error.

and i don't know it is needed or not but i have changed my apache2 default port to 8080, nginx default port to 80 and below is my nginx reverse proxy configuration but i don't know this configuration correct or not. after proxypass changed to 8000, npm start working in the server.Then app running in http://localhost:8000 in server. but how can i access the site in server with localhost? i called http:///explorer/app but it shows only the header links and footer links.

location /explorer/app { proxy_pass http://localhost:8000; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection 'upgrade'; proxy_set_header Host $host; proxy_cache_bypass $http_upgrade;

First attempt to serve request as file,

            then
    # as directory, then fall back to
            #displaying a 404.
    try_files $uri $uri/ =404;
}
