How to listen to ipv6 addresses for two domains in nginx?

Question

Nginx

Hello. I'm trying to make two domains available via IPV6. There are two configs: the first site and the second.
Both files (with the exception of the server_namessl settings) contain the following lines:

server {
  listen 80;
  listen [::]:80 ipv6only=on;

  ...
}

server {
  listen 443;
  listen [::]:443 ipv6only=on;

  ...
}

There is also a third config for processing requests directly on the server IP itself:

server {
  listen 80 default_server;
  listen [::]:80 ipv6only=on;

  server_name localhost;

  root /var/www/http;
}

When trying to start the server, nginx swears and says that duplicate listen options for [::]:443. Don't understand why duplicate if I want to listen on ipv6 on both sites. How to fix the situation, tell me, please?

Answer 1

ipv6only=oncan only be specified once per ip:port pair
