I've tried to troubleshoot the problem with no luck

I have restarted the server checked logs rewritten my config file multiple times with no luck

i followed this url to the T and i still cant seem to trouble shoot the problem

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

        # include snippets/snakeoil.conf;

        root /var/www/html;

        # Add index.php to the list if you are using PHP
        index index.html index.htm index.nginx-debian.html;

        server_name telebotstools.io www.telebotstools.io;

   location / {
        proxy_pass http://localhost:8080; #whatever port your app runs on
        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;
    }

Thanks in advance
