Nginx redirect from old subdomain to new subdomain

Question

I want to redirect all traffic from old subdomain to new subdomain but something went wrong =)

Here is my config:

# Redirect from http to https
server {
  listen 80 default deferred; # for Linux
  return 301 https://$host$request_uri;
}

# Redirect section - from old to new sub
server {
  listen 80;
  listen 443 ssl http2;

  server_name old.domain.com www.old.domain.com;
  return 301 https://new.domain.com$request_uri;

  # should I use SSL while redirecting? without old certs nginx gives me an error...
  ssl_certificate ...
  ...
}

# main working subdomain
server {
  listen 443 ssl http2;
  server_name new.domain.com www.new.domain.com;
  root ...
  ...
}

With this config I can access to new.domain.com and it is working as expected with valid SSL cert, but old old.domain.com is also accessible without redirection :(

Answer 1

My variant is working, it was an error on DNS provider side (something was wrong with DNS records, CNAME)
