Edge Certificate validation

Regarding this error, kindly re-check this possible solution if the domain was recently added to Cloudflare from below.

May I ask have you had an SSL certificate already installed at your host/origin server before moving to Cloudflare?

What SSL options have you got selected under SSL tab/settings page at your Cloudflare dashboard?

Moreover, kindly try clearing your Web browser cache and restarting your router.

If you go to SSL/TLS > Edge Certificates in your Cloudflare dashboard, you may see the certificate showing the certificate as ‘Pending Validation’ rather than ‘Active’:

It can take up to 24hrs for the free Universal SSL certificate to provision, if it has been longer than that, try disabling and re-enabling Universal SSL to restart the process.

Thanks for ticket number. Maybe @cloonan could take a look, if so.
