I'd like to add ssl certificate to my django app. I've followed tutorial so the nginx config for domain was changed but now it looks like generated certificate is incorrect.

nginx conf before certbot modifications

server {
    listen 80;
    listen [::]:80;
    server_name doamin.com www.domain.com;


    location = /favicon.ico { access_log off; log_not_found off; }
    location /static/ {
        root /home/poul3r/doamin.com;
    }

    location / {
        include proxy_params;
        proxy_pass http://unix:/run/gunicorn.sock;
    }
}

and after certbot action

server {
    server_name doamin.com www.doamin.com;


    location = /favicon.ico { access_log off; log_not_found off; }
    location /static/ {
        root /home/poul3r/doamin.com;
    }

    location / {
        include proxy_params;
        proxy_pass http://unix:/run/gunicorn.sock;
    }



    listen [::]:443 ssl ipv6only=on; # managed by Certbot
    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/doamin.com/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/doamin.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 ($host = doamin.com) {
        return 301 https://$host$request_uri;
    } # managed by Certbot


    listen 80;
    listen [::]:80;
    server_name doamin.com www.doamin.com;
    return 404; # managed by Certbot
}

What I'm doing wrong or what could went wrong during letsencypt implementation ?
