Cloudflare ssl and site redirect to www

Hi my Friends, recently I buy a new host from siteground and i use also cloudflare... now on edge certifications I have it active on www and non-www is pending.

Only when i visit the site with https://site.com (non www) i receive "Your connection is not private" but if I visit without HTTPS only http://site.com i`m redirect to https://www.site.com, and is ok ( this url is configured on wordpress)

Now to solve this i will redirect with page rules non-www to www but my question is how to solve on CloudFlare Edge Certification for site.com ( without www ) or is ok to leave it like this ?

Update:

I solved... SSL from siteground was not installed ) now is fine
