May I ask what SSL option have you got selected under the SSL/TLS tab at Cloudflare dashboard for your domain ( Flexible, Full, Full Strict … )?

Before moving to Cloudflare, was your Website working over HTTPS connection?

Before doing anything at Cloudfalre settings, you could determine if you have a valid SSL certificate installed at the origin host/server by your web hosting provider or your own VPS/dedicated server following the steps from below:

1. Use the “Pause Cloudflare on Site” option from the Overview tab for your domain at dash.cloudflare.com .
2. The link is in the lower right corner of that page.
3. Give it five minutes to take effect.
4. Check with your hosting provider / cPanel AutoSSL / ACME.sh / Certbot / Let’s Encrypt or some other and renew it accordingly.
5. Make sure site is working as expected without any errors via HTTPS.
6. Only then should you un-pause Cloudflare and double-check your SSL/TLS setting to make sure it’s Full (Strict).

Here is a way to re-check if you correctly setup the SSL for your domain with Cloudflare:
