NGINX SSL set up

Trying to add a SSL certificate to a site, it was working before the SSL but now trying to connect it times out. My nginx conf file is

    listen 80 default_server;
    listen [::]:80;

    server_name gpsuk.net;

    # Redirect all HTTP requests to HTTPS with a 301 Moved Permanently response.
    return 301 https://$host$request_uri;
}

server {
    listen 443 ssl http2;
    listen [::]:443 ssl http2;
