Hey,
I successfully was able to set online a website in https ; but when I try to put a second one I get the following error :

""
[alert] 27063#0: worker process 27157 exited on signal 11
""

...Multiple time until the client does timeout.
There is the two https part, the two of them work if I disable one or another.
What am I missing ? :(

""
server {
server_name arzinfo.pwnz.org;
listen 443 ssl default_server;
listen [::]:443 default_server;#ipv6only=on;

index index.php index.html;
root /srv/arzinfo.pwnz.org;

ssl_certificate /etc/letsencrypt/live/arzinfo.pwnz.org/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/arzinfo.pwnz.org/privkey.pem;
ssl_trusted_certificate /etc/letsencrypt/live/arzinfo.pwnz.org/fullchain.pem;

try_files $uri $uri/ =404;
}
}

Second one :
""
server {
server_name otyugh.pwnz.org;
listen 443 ssl;
listen [::]:443;#ipv6only=on;

index index.php index.html;

ssl_trusted_certificate /etc/letsencrypt/live/otyugh.pwnz.org/fullchain.pem;
location / {
try_files $uri $uri/ =404;
}
}

...Ok. Just made it work. It missed something I did not even include here (it was tls tweaks I thought unimportant on the issue)

this snippet :

""
ssl_protocols TLSv1.2;
ssl_prefer_server_ciphers on;
ssl_ciphers 'ECDHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-SHA384:ECDHE-RSA-AES256-SHA:ECDHE-RSA-CHACHA20-POLY1305';

add_header Strict-Transport-Security "max-age=15768000; includeSubdomains; preload";
add_header X-Frame-Options DENY;
add_header X-Content-Type-Options nosniff;

I don't understand why this solve the problem, but it does. Maybe the tickets off ? No idea.
