Nginx doesn't see or use subdomain config

yt flag

Problem: nginx doesn't apply configuration for subdomain if there are domain and subdomain config at the same time.

Disclaimer: I'm new to nginx and server deployment.

Question: What I do wrong with nginx configuration?

Additional info:

  • Nginx 1.18.0
  • Ubuntu 20.04

Details:
I have main domain (it's my portfolio) (let's say example.com) and subdomain (todo-tracker.example.com). Both are django projects started with gunicorn (main on 127.0.0.1:8000, todo-tracker on 127.0.0.1:8001).

I have two sites-available config files:

  • default - for main domain
    server {
        server_name example.com;

        location / {
            proxy_pass http://127.0.0.1:8000/;
            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;
        }

        location /static {
            autoindex on;
            alias /home/portfolio/portfolio/staticfiles;
        }

        listen [::]:443 ssl ipv6only=on; # managed by Certbot
        listen 443 ssl; # managed by Certbot
        ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem; # managed by Certbot
        ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem; # managed by Certbot
        include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
        ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
    }

    server {
        if ($host = example.com) {
            return 301 https://$host$request_uri;
        } # managed by Certbot

        listen 80;
        listen [::]:80 ipv6only=on;
        server_name example.com;
        return 404; # managed by Certbot
    }
  • todo-tracker - for subdomain
    server {
        server_name todo-tracker.example.com;

        location / {
               proxy_pass http://127.0.0.1:8001/;
               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;
        }
    }

Both files passes nginx -t test. Both files are added to sites-enabled with symbolic links and both are valid.

I've conducted some experiments:

  1. If I remove todo-tracker config file and put configuration in default config like this, it redirects just fine and opens my todo-tracker, however in this case I don't have access to portfolio.
    server {
        server_name todo-tracker.example.com;
    
        location / {
               proxy_pass http://127.0.0.1:8001/;
               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;
        }
    ... ssl config ...
  1. I've removed default config and kept only todo-tracker one. In this case it didn't work at all, so I made the conclusion that todo-tracker's config doesn't load properly.
  2. I've also tried to combine two files (i.e. just copy subdomain config into default config file). In this case main domain loaded successfully and subdomain was proxied to main domain so that it returned the django error "add to allowed hosts".

Please add output of `nginx -T` (note capital case) to show the complete nginx configuration.

@TeroKilkanen Add it at the bottom of the question. Hope I did it right.

Your configuration for todo-tracker is missing the listen directive(s).

thanks. I created a new ssl certificate for my subdomain and it worked!

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
