Website inaccessible after installing Let's encrypt certificate

Hello, I set up a droplet and configured nginx to serve a small static website. Everything was working fine until I installed a certificate using the Certbot script.

This is the nginx configuration file for the website:

server {

    root /var/www/angelacapillo.com;
    index index.php index.html index.htm;

    server_name angelacapillo.com www.angelacapillo.com;

    location / {
        try_files $uri $uri/ =404;
    }

    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/angelacapillo.com/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/angelacapillo.com/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
}

server {
    if ($host = www.angelacapillo.com) {
        return 301 https://$host$request_uri;
    } # managed by Certbot

    if ($host = angelacapillo.com) {
        return 301 https://$host$request_uri;
    } # managed by Certbot

    server_name angelacapillo.com www.angelacapillo.com;
    listen 80;
    return 404; # managed by Certbot
}

Following their instructions, I tested the certificate here but I get an error: https://www.ssllabs.com/ssltest/analyze.html?d=www.angelacapillo.com

What might be the issue?
