2460	listen 443 ssl precedence	https://stackoverflow.com/users/12360980/logi		"Hi,
I belive this is a bug.

Using `listen ... ssl` in a single vhost server block forces every other vhost (even defined in a different file!) with same port listening to apply ssl-related directives, i.e.:

`nginx[343400]: nginx: [emerg] no ""ssl_certificate"" is defined for the ""listen ... ssl"" directive in /etc/nginx/sites-enabled/aaa-default.conf:1`
{{{
/etc/nginx/sites-enabled #: cat aaa-default.conf 
server {

    listen 80;
    listen 443;
    server_name _;
}
}}}
and the other file, that using ssl:
{{{
server {
    # Update this line to be your domain
    listen 80;
    server_name xxx.domain.tld;
}

server {
    listen 443 ssl;
    server_name xxx.domain.tld;

    ssl_dhparam /etc/nginx/ssl/dhparams.pem;

    add_header Strict-Transport-Security ""max-age=31536000; includeSubdomains"";
    ssl_prefer_server_ciphers on;
    ssl_session_cache shared:SSL:10m;

    proxy_buffering off;

    location / {
        proxy_pass ht_t_ps:_/_/xxx.xxx.xxx.xxx; #Maximum number of external links per post exceeded
        proxy_set_header Host $host;
        proxy_redirect ht_tp:// htt_ps://;
        proxy_http_version 1.1;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection $connection_upgrade;
    }
}

}}}
{{{
/etc/nginx/sites-enabled #: cat ../inc/ssl.conf 
#ssl on;

ssl_certificate /root/.acme.sh/logiczny.it/fullchain.cer;
ssl_certificate_key /root/.acme.sh/logiczny.it/logiczny.it.key;

ssl_protocols TLSv1.2 TLSv1.3;
ssl_ciphers         HIGH:!aNULL:!MD5;
}}}
I can observe same behaviour, no matter what port I setup to listen on ssl (80 acts identical), so I strongly belive that adding `ssl` to `listen` directive causing that. 

Is that how this suppose to work?"	defect	closed	trivial		nginx-core	1.18.x	invalid		https://stackoverflow.com/users/12360980/logi	Linux xxx 5.10.0-20-amd64 #1 SMP Debian 5.10.158-2 (2022-12-13) x86_64 GNU/Linux	"nginx version: nginx/1.18.0
