Question

I've containerized the next.js web application and hosted in aws ec-2. using nginx as proxy server

this is the only working page

/

not working for any other pages (paths),it throws 502 bad-gate-way

EX:

/etc

/slug/page

this is the nginx cofiguration

server {
listen 80 default_server;


location  / {
  proxy_pass http://localhost:300;
}

}

how can I Forward all paths to a specific port?

Answer 1

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

        root /var/www/html;
        index index.html index.htm index.nginx-debian.html;

        server_name _;

        location / {
                # reverse proxy for next server
                proxy_pass http://localhost:300;
                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;

            # we need to remove this 404 handling
                # because next's _next folder and own handling
                # try_files $uri $uri/ =404;
        } 

        location ~ /.well-known {
                allow all
        }
} 

I've add this nginx configuration, now it's working fine.
