Nginx wildcard subdomain

cn flag
Al Malik Umair

I have setup my nginx config file as:

server {
   server_name example.com www.example.com;
   listen 80;
   
   location = / {
     .....
  }
}

server {
  server_name *.example.com;
  listen 80;
  location = / {
      proxy_pass ...
  }
}

browsing through example.com and www.example.com is fine, but when I use some subdomain like a.example.com or b.example.com I get a message like "301 moved permanently" and I am redirected back to example.com

Here is the actual file;

Show full config with `nginx -T`. Also, make sure that `a.example.com` and `b.example.com` DNS records are pointing to the same server as `example.com` and `www.example.com`.

Actually, no subdomain is working in my case, not even www.example.com, only example.com is functional

There is no redirect configured in your nginx configuration. The redirect most probably comes from your backend server.

The configuration for *.billspree.work is incorrect.

listen 80 ssl;

means that nginx is configured to use TLS on port 80, which is not a valid configuration.

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.
