NGINX - https for two domains and letsencrypt

Question

I am a noob when it comes to Linux and nginx, so my question maybe as basic as it sounds.

So I have two domains domain1.com and domain2.com both pointing to my server. I have obtained a certificate via letsencrypt for each of the two. How can I install each of those for each of the domains?

I have searched the internet and had no luck. So far I came up with this

Config 1:

server {
    server_name domain1.com;

    ssl_certificate path/to/cert;
    ssl_certificate_key path/to/cert/key;
}

Config two:

server {
    server_name domain2.com;

    ssl_certificate path/to/cert2;
    ssl_certificate_key path/to/cert/key2;
}

The default config:

server {
    listen 80 default_server;
    listen [::]:80 default_server;

    listen 443 ssl default_server;
    listen [::]:443 ssl default_server;

    root /var/www/html;
}

I have created one for both. One doamin was already configured and works fine. But the second can not reach domain2.com via https:// and also the domain points to the default side.

TL;DR How can I use two certificates for two domains on one nginx instance?

Thanks!

EDIT: All other configs are pretty much the basic ones you get with the installation.

Answer 1

You need to add bindings to each of the server blocks:

listen myipaddress:443 ssl http2;

The first site is catching the traffic. You can use the same IP but just need to check that the nginx version supports SNI (should do if a recent version)
