Create two server blocks. Put the www server name before the \* and it  
should work:

See [Server names](http://nginx.org/en/docs/http/server_names.html)

Exact names precede patterns or regex server names.

server {

   server_name www.example.com;

```

}

server {  
## This is to avoid the spurious if for sub-domain name  
## rewriting. See [GitHub - nginxinc/nginx-wiki: ARCHIVED -- Source for the now archived NGINX Wiki section of https://www.nginx.com · GitHub](http://wiki.nginx.org/Pitfalls#Server_Name).  
listen [::]:80; # ipv6  
server\_name \*.example.com;  
rewrite ^ $scheme://www.example.com$request\_uri permanent;  
} # server domain rewrite.

I haven’t tried it myself. Try it.

It doesn’t work. With server\_name [www.example.org](http://www.example.org) and server\_name  
\*.example.org my site doesn’t redirect [blabla.example.org](http://blabla.example.org) to  
[www.example.org](http://www.example.org)
