HTTPS / SSL still not set for my domain, even after few hours

Hello,

I set my domain scgupta.me a few hours back, but "Https (SSL)" status is still "SSL Certificate not active yet."

If I understood correctly, all domains in all plans, a FREE SSL certificate offered by Let's Encrypt authority is set automatically.

Do I need to do something? Can you please help setting SSL so that I can create and share https links?
Thanks.
