Greetings,

Thank you for asking.

May I ask was your Website working fine over HTTPS both non-www and www prior activating to Cloudflare?

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 … )?

Make sure it’s Full (Strict).

SSL certificate seems to be okay for both non-www and www version of your domain name:

Server certificate:
subject: CN=thekitchenmakeovershop.com
start date: Aug 11 23:11:04 2024 GMT
expire date: Nov  9 23:11:03 2024 GMT
subjectAltName: host "www.thekitchenmakeovershop.com" matched cert's "*.thekitchenmakeovershop.com"
issuer: C=US; O=Let's Encrypt; CN=R11
SSL certificate verify ok.
...
> GET / HTTP/2
> Host: www.thekitchenmakeovershop.com
> User-Agent: curl/8.6.0
> Accept: */*
>
< HTTP/2 200

Furthermore, there seems to be some redirection caused by the WordPress from non-www to www (which seems to be okay as well), despite you’re using WP Super Page Cache plugin for caching indeed:

x-wp-cf-super-cache: disabled
x-redirect-by: WordPress

Community Tip - Fixing ERR SSL VERSION OR CIPHER MISMATCH in Google Chrome

Error Try the suggestions in this Community Tip to help you fix ERR SSL VERSION OR CIPHER MISMATCH in Chrome. Background A website using HTTPS performs a series of steps between the browser and the web server to ensure the certificate and SSL/TLS connection is valid. These include a TLS handshake, the certificate being checked against the certificate authority, and decryption of the certificate.

I’d suggest you to temporary Pause Cloudflare for your site. Wait few minutes. Double-check the origin SSL certificate. Renew it. After the Website works okay over HTTPS, un-pause and all good.

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 without any error
4. Check with your hosting provider / cPanel AutoSSL / Let’s Encrypt / ACME / Certbot and manually click to renew it
5. Only then, when your website responds over HTTPS, you should un-pause Cloudflare and double-check your SSL/TLS setting to make sure it’s Full (Strict).
