Support Namecheap domains SSL

It seems that if you buy domain from Namecheap and CNAME the www record to cloudflare worker, there will be an SSL error.

curl -v https://www.themilest.one
* Connected to (nil) (127.0.0.1) port 7890 (#0)

I solved the issue like this.

But since I'm providing service to customers thru cloudflare for SaaS custom hostnames. I will lose a lot of customers if they need the extra step. Is it possible that Cloudflare natively support this?
