Use Flexible SSL with a .sl Domain

How can i use the Cloudflare SSL Certificate with my .sl domain?

It don’t works

Unfortunately, Comodo cannot issue a certificate to the SL ccTLD due to US Export Laws. Center/Article/View/989/66/banned-country-list

If you want to use a certificate, you’ll need to install a certificate from a non-US CA at your origin and grey-cloud your domain or install the certificate at Cloudflare if you are on Business or Enterprise plan.

From what I heard, Let’s Encrypt can issue a certificate to those banned ccTLD. You might want to try this route if SSL is of utmost importance to you.
