nginx and SSL: 502 bad gateway

Question

I really hope you guys can help me out. I lost my way around different guides of setting up ssl.

When I try to access my site i just get 502 Bad Gateway. Plain old nginx works just fine, and "simple" ssl without forces ssl also works fine.

Here are my config files.

default.conf

## http://xn--srentorp-54a.dk redirects to https://xn--srentorp-54a.dk
server {
    listen 80;
    listen [::]:80;
    server_name xn--srentorp-54a.dk;

    include /etc/nginx/snippets/letsencrypt.conf;

    location / {
        return 301 https://xn--srentorp-54a.dk$request_uri;
    }
}

## http://www.xn--srentorp-54a.dk redirects to https://www.xn--srentorp-54a.dk
server {
    listen 80 default_server;
    listen [::]:80 default_server ipv6only=on;
    server_name www.xn--srentorp-54a.dk;

    include /etc/nginx/snippets/letsencrypt.conf;

    location / {
        return 301 https://www.xn--srentorp-54a.dk$request_uri;
    }
}
