SSL issue in subdomain with www



My website has 2 subdomains and, they all work fine.
But when I use or then bowser shows security error.


The certificate Cloudflare provide for you only cover for * For sub-subdomain, you’ll need to purchase Cloudflare Dedicated SSL with Custom Hostname for $10/month.

Alternatively, if you are in Business or Enterprise plan, you can upload your own custom SSL certificate.


How about creating Page Rules that redirect any www to the non-www? Something like:
https://www.** redirect to https://$$2


Have you tried it?


That’s something you would have to try from the Page Rules tab in your Cloudflare account.
