About asp.net : Aspnet-core-MVC-with-Identity-hosting-on-Linux-with-Nginx

I’m trying to host an ASP.net core MVC app on Linux using Nginx. I managed to host a sample MVC app without User authentication, but when I wanted to host one with Identity built in, it results with http 500 internal server error.
The app is running, the nginx codes are ok. Help me out here.

I’m hosting on command only debian operating system.

This is my nginx/sites-available/default configuration

server {
listen        80;
server_name   example.com *.example.com;

    location ~ ^/(css/|lib/|js/|favicon.ico/){
            root /var/www/aspnetcoreapp/wwwroot;
            access_log off;
            expires max;
    }

     location / {
    proxy_pass         http://127.0.0.1:5000;
    proxy_http_version 1.1;
    proxy_set_header   Upgrade $http_upgrade;
    proxy_set_header   Connection keep-alive;
    proxy_set_header   Host $host;
    proxy_cache_bypass $http_upgrade;
    proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header   X-Forwarded-Proto $scheme;
}

}
