Configure nginx for websocket

you have to complete these before the next step to allow websocket connection.

• you have completed the basic NGINX installation

• you have configured the DNS setting to point to your IP address

• you have created the SSL certificate for your domain

• you have enabled the UFW setting for HTTP Full

At this stage, when you input your domain address on the browser, this is what you should see 👍

Your Domain has a Secured connection

Add the code to UPDATE the vivaldi configuration file

      proxy_buffering off;
      proxy_pass http://localhost:9944;
      proxy_set_header X-Real-IP $remote_addr;
      proxy_set_header Host $host;
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

      proxy_http_version 1.1;
      proxy_set_header Upgrade $http_upgrade;
      proxy_set_header Connection "upgrade";
      

sudo nano /etc/nginx/sites-available/vivaldi.network

this is what it will look like :

location / {
      try_files $uri $uri/ =404;

      proxy_buffering off;
      proxy_pass http://localhost:9944;
      proxy_set_header X-Real-IP $remote_addr;
      proxy_set_header Host $host;
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

      proxy_http_version 1.1;
      proxy_set_header Upgrade $http_upgrade;
      proxy_set_header Connection "upgrade";
      
}

    listen [::]:443 ssl ipv6only=on; # managed by Certbot
    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/vivaldi.network/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/vivaldi.network/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot


}

Remember to restart NGINX

sudo nginx -t
sudo systemctl restart nginx

When you have restarted NGINX, you will notice that your browser will show an error when you try to access the domain (this is normal)

When you have successfully built and run your node, your domain will look like this:
