http status code 502 – nginx: 502 bad gateway if /index.html is not in URL – Stack Overflow

i don’t understand what i’m doing wrong so i hope somebody can help 🙂

When i access http://10.0.0.54/index.html i get the right page but if i try to access http://10.0.0.54 instead of showing the index file it redirects me to https://10.0.0.54 showing error 502 bad gateway.

This is the configuration /etc/nginx/sites-available/default

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

        root /var/www/html/salvaderi;

        index index.html;

        server_name _;

        location ~ /.well-known/acme-challenge {
                allow all;
                root /var/www/html/salvaderi;
        }

        location / {
                root /var/www/html/salvaderi;
                index index.html;
        }
}

I am running nginx 1.18.0 on ubuntu 22.04

i tried changing parameters inside location /{} but i always get the same result. I also changed the root directory and made sure permission where set right. Searching on for the solution i saw other people having problems about PHP and FastCGI but i am not using it.
