I've written a sailsjs based application, deployed in one of my VPS. App is running in production mode using pm2. I can access through public_ip:1338, everything seems normal.
So installed nginx,configured proxy_pass, installed letsencrypt ssl. When I'm trying to access domain, I'm seeing Nginx Default Page with SSL working, not the NodeJS (SailsJS) application.
Here is nginx conf file
server {
    listen 80;
    server_name domain.net www.domain.net;
    return 301 https://$server_name$request_uri;
}
server {
    listen 443 ssl spdy;
    listen [::]:443 ssl spdy;
    ssl_certificate     /etc/letsencrypt/live/domain.net/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/domain.net/privkey.pem;
    server_name domain.net;
    location / {
        proxy_pass http://localhost:1338;
        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;
    }
}
I need to sort out the issue. Can you guys instruct me to fix the issue?
