Running Go server behind Nginx Reverse Proxy with SSL

Question

I've done some digging through the interwebs and haven't been able to come across anything similar (at least near any solution that has worked out for me).

Essentially, I am running a Golang server locally on 127.0.0.1:1337 , I want this to be accessible globally so I use Nginx to forward traffic from https://api.example.com/ to my API to retrieve information.

With that being said, I have simply setup my Golang server to listen and serve on port 1337 and my Nginx configuration is setup to redirect all HTTP traffic (for all domains) to HTTPS:

server {
    listen 80 default_server;

    server_name _; 
    return 301 https://$host$request_uri;
}

and then I redirect traffic to port 1337 here:

server {
    server_name api.example.com;
    location / {
        proxy_pass http://127.0.0.1:1337;
    }

    listen 443 ssl;
    ssl_certificate_key /etc/nginx/ssl/private.key;
    ssl_certificate /etc/nginx/ssl/cert.crt;   
}

The issue with this is that I find myself to keep getting redirects from HTTPS to HTTP (as per wget ) and I end up getting a Too Many Redirects error.

If anyone can provide some guidance, I'd very much appreciate it!

Answer 1

server_name _; matches server name that can not find matches.

I have done that before.

See my nginx config to proxy api backend:

# ssl
ssl_certificate      /etc/nginx/cert/live/ybilly.com/fullchain.pem;
ssl_certificate_key  /etc/nginx/cert/live/ybilly.com/privkey.pem;

# http to https
server {
  listen 80 default_server;
  listen [::]:80 default_server;
  server_name ybilly.com www.ybilly.com *.ybilly.com;
  return 301 https://$host$request_uri;
}

# api backend
server {
  listen 443 ssl http2;
  listen [::]:443 ssl http2;
  server_name *.ybilly.com;

  location / {
    add_header Access-Control-Allow-Origin *;
    add_header Access-Control-Allow-Methods 'GET, POST, OPTIONS';
    add_header Access-Control-Allow-Headers 'DNT,X-Mx-ReqToken,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Authorization';
    proxy_set_header Host $host;
    proxy_set_header X-Real-Ip $remote_addr;
    proxy_set_header X-Forwarded-For $remote_addr;
    proxy_pass_header Set-Cookie;
    proxy_read_timeout                 900;
    proxy_buffers 32 4k;
    proxy_pass http://127.0.0.1:8080/;
  }

}
