When you tested your domain using the Cloudflare Diagnostic Center, what were the results?
This link doesn’t work.

Describe the issue you are having:

We enabled Cloudflare for the first time on 18th March. Around 18-20th May the web started to give a SSL error, Not secure, to some users when using cloudflare, when we reset the nameservers to the ones for the hosting to remove Cloudflare everything works fine.

What error message or number are you receiving?
Translation: The connection is not privated
It is possible that atackers are trying to steal your information…
Obviously this is a really bad thing for a website that sells infoproducts.

What steps have you taken to resolve the issue?

  1. Try diferent browsers. Some work and some others doesn’t both PC and smartphones.
  2. Review the settings
  3. Activate Developer mode - Doesn’t solve the problem.
  4. Remove Cloudflare → This solved the problem.
  5. Open a ticket to the hosting: They reviewed both sever settings and cloudflare settings (SSL and DNS) and said everything looks fine.
  6. We activated Cloudflare again, and the problem started again.
  7. We checked browser versions from one person where it doesn’t work and it is the same as mine (webmaster) and for me works fine both in computer and smartphone. Diferent internet connections.
  8. Removed cloudlfare nameservers again and it works.

Was the site working with SSL prior to adding it to Cloudflare?
Yes, and also with Cloudflare for a month.

What are the steps to reproduce the error:

Just accessing the url but from specific persons or browsers.

Browser Information from a person where the error appears, web shows as not safe. Same version as mine where it worked at that same time:

Have you tried from another browser and/or incognito mode?

Please attach a screenshot of the error:
The sistem doesn’t allow me to send more images.

The error on some other device accessing the website link from Instagram says:

Error de seguridad - Hay problemas con el certificado de seguridad de este sitio. Volver.
Security error - There are problems with this site SSL certificate. Return.

Thanks in advance for the help and best regards,

Taisa - Webdesigner and Webmaster

What is the error?

It’s on the text, the forum didn’t allow me to upload the images or add links before:

Error de seguridad - Hay problemas con el certificado de seguridad de este sitio. Volver.
Security error - There are problems with this site SSL certificate. Return.

Now I can.

Also other person had this one:

This is likely due to the Google Trust Services certificate issue that was identified last week.

We became aware of a compatibility issue with some types of Google Trust Services certificates where certificates would show as invalid on certain older devices or systems with older trust stores. We made our partner aware of this and have temporarily stopped issuing these types of certificates.

If you’re experiencing this issue with a certificate issued before 2023-05-19 21:15 UTC, we suggest you replace the certificate by disabling Universal SSL (which will remove the incompatible certificate) and then re-enable Universal SSL (which will generate a new, more ubiquitous certificate).

You may disable and re-enable Universal SSL on your Dashboard at the bottom of the SSL/TLS > Edge Certificates page.


Ok, that makes totally sense. I will tell the customer, but it is a problem on a site that sells a lot of infoproducts that it fails, beucause that becomes to lost sales…
