I originally configured the nodejs app on the rpi2 behind a linksys router and the app responded fine from an outside server.

Then I installed nginx and added https with a certificate from letsencrypt and it served the https site just fine to my Mac on the same network.

Now that I'm trying to combine the two, but it's not working, I get a 404 not found. My app is at:

/www/subdomain.domain.com/aism/app.js

The nginx config for that /etc/nginx/sites-available/subdomain.domain.com is as follows:

[code]
server {
listen 80;
listen [::]:80;
server_name subdomain.domain.com;
return 301 https://$server_name$request_uri;
}

server {
listen 443 ssl;
listen [::]:443 ssl;
server_name subdomain.domain.com;

ssl_certificate /etc/letsencrypt/live/subdomain.domain.com/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/subdomain.domain.com/privkey.pem;

root /www/subdomain.domain.com;
index index.php index.html index.htm;

error_page 404 /404.html;
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /www/subdomain.domain.com;
}

# Error & Access logs
error_log /www/subdomain.domain.com/logs/error.log error;
access_log /www/subdomain.domain.com/logs/access.log;

location / {

proxy_set_header Host $host;

}

location ~ /.well-known {

}

}
}

I just checked the error log and it looks like this:

[code]
2017/04/23 19:30:48 [error] 20219#0: *1 upstream prematurely closed connection while reading response header from upstream, c$
2017/04/23 19:30:48 [error] 20219#0: *1 open() "/www/subdomain.domain.com/aism/50x.html" failed (2: No such file or directory$
[/code]

I removed the 50x.html line in the config. Now I get this bad gateway error from hurl.it & the error log on the pi looks like this:

2017/04/23 19:48:27 [error] 20302#0: *1 upstream prematurely closed connection while reading response header from upstream, client: 23.20.198.108, server: subdomain.domain.com, request: "POST /API/switches/sw1?password=123456 HTTP/1.1", upstream: "http://192.168.1.53:442/API/switches/sw1?password=123456", host: "subdomain.domain.com"
2017/04/23 19:48:27 [error] 20302#0: *1 upstream prematurely closed connection while reading response header from upstream, client: 23.20.198.108, server: subdomain.domain.com, request: "POST /API/switches/sw1?password=123456 HTTP/1.1", upstream: "http://192.168.1.53:442/50x.html", host: "subdomain.domain.com"

Thats the correct localLanIP for the rpi and the 442 port is whats configured in the .env file for the app.js to listen for.

Here is the setup!
