NGINX 404 not found but file exists

I want to call the index.html from the folder /var/www/fileUpload/html. The index.html file exists in that folder.

The / router works. the uploadFiles route as well. But when I open the upload route I get a 404 error.

    server{
    listen 80;
    server_name xx.xx.xxx.xxx;

    location / {
        root /var/www/kioskJPE/html;
        index index.html;
    }
    location /upload {
        root /var/www/fileUpload/html;
        index index.html;
    }
    location /uploadFiles {
        proxy_pass http://localhost:8080;
        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;
    }
}

Do you have any suggestions? Thank you!

Answer

That should be alias /var/www/fileUpload/html; otherwise Nginx is looking for the file in /var/www/fileUpload/html/upload/index.html. See this document for details.

For example:

location /upload {
    alias /var/www/fileUpload/html;
}
