When I am working on word press for my website

May I ask if the rest of the domain is working ok?
Is this error on some particular request or plugin or WP admin?

my hosting company

May I ask if you can ask them if Cloudflare IPs are allowed at the origin host/server from them? Here is the article:

• https://support.cloudflare.com/hc/en-us/articles/201897700-Allowing-Cloudflare-IP-addresses

Nevertheless, Cloudflare IP addresses list can be found here:

• https://www.cloudflare.com/ips/

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

Kindly, 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, then make sure site is working as expected with HTTPS.
4. Check with your hosting provider / cPanel AutoSSL / ACME.sh / Certbot / Let’s Encrypt or some other and renew it accordingly.
5. Only then should you un-pause Cloudflare and double-check your SSL/TLS setting to make sure it’s Full (Strict).

Could you also write back if your WordPress is configured with “home_url” and “site_url” in the “Options” and working fine over a HTTPS in a different Web browser just for testing purposes.

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 … )?
