How to reset cached redirect in nginx?

Question

Nginx

Set up a redirect from server.com to www.server.com in this way

server {
    server_name “~^(?!www\.).*” ;
    return 301 $scheme://www.$host$request_uri;
}

And now, when a request is made to www.server.com, it is redirected to www.www.server.com. I have already removed these settings from the config, but the redirection remains.
What could be the reason?

Answer 1

Also, restart the browser, because 301 redirects can be cached.

Answer 2

sudo service nginx reload
