Deploying multiple domains using nginx

I've been searching for a while to fix this issue but I can't seem to figure it out.

So basically, I've just bought a new domain and I am looking to host it on the same server I am hosting my other one on. However, I seem to be coming across this bug where whenever I try to load my second domain, it loads for a bit then gives me a cloudflare timeout error (522). My first domain always loads correctly though. I did notice something weird though, whenever I remove the first server {} block, it starts loading what is supposed to be loaded on my second domain, on my first. Anywho, here's my config:

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

    listen 443 ssl;
    listen [::]:443 ssl;
    ssl on;
    ssl_certificate /etc/ssl/certs/server_pnyxdev.pem;
    ssl_certificate_key /etc/ssl/private/server_pnyxdev.key;

    root /var/www/html/pnyxdev;

    index index.php index.html;

    server_name pnyx.dev;

    location / {
        proxy_pass    http://localhost:18528/;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
        # try_files $uri $uri/ =404;
    }

    location ~ \.php$ {
        include snippets/fastcgi-php.conf;
        fastcgi_pass unix:/var/run/php/php7.3-fpm.sock;
    }

    location ~ /\.ht {
        deny all;
    }
}

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

    listen 443 ssl;
    listen [::]:443 ssl;
    ssl on;
    ssl_certificate /etc/ssl/certs/server_ethanpro.pem;
    ssl_certificate_key /etc/ssl/private/server_ethanpro.key;

    root /var/www/html/ethanpro;

    index index.php index.html;

    server_name ethan.pro;

    location / {
        proxy_pass    http://localhost:1234/;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host "ethan.pro";
        proxy_cache_bypass $http_upgrade;
        # try_files $uri $uri/ =404;
    }

    location ~ /\.ht {
        deny all;
    }
}
