When it comes to NGINX, ideally you'll want to separate the server blocks--one for serving requests on port 80 (which redirects to 443) and one for port 443.

Instead of using the domain, I would recommend using $host combined with $request_uri.

Additionally, looking to your configuration, I see that you are pulling the CloudFlare IP. Since CloudFlare natively provides SSL, you'll want to make sure you're set to use Strict mode so that you avoid the infinite loop.

It may take a few minutes for the Strict mode to take effect, and you may need to fully clear your browser cache before you'll be able to utilize the new 301 redirect.

Example (using the configuration you provided)

server {
    listen 80;
    server_name domain.com www.domain.com;

    #
    # No additional configuration needed. This block only exists to redirect
    # requests to port 443 (SSL).
    #

    return 301 https://$host$request_uri;
}

server {
    listen 443 ssl;
    server_name domain.com www.domain.com;

    root /var/www/domain1.com;

    real_ip_header CF-Connecting-IP;
