Err ssl version

Hello there CF community!

From yesterday I have a strange error.

I have a website that has a Lets Encrypt certificate which is valid.

If I do not proxy through cloudflare I can visit the SSL version of it correctly.

When I proxy it through CF, I get an ERR_SSL_VERSION_OR_CIPHER_MISMATCH error. If I unproxy it, it works correctly.

  • The site has been proxied through CF for like 2 years now without any problem.
  • On the Edge Certificates, the Universal certificate stays at “Pending Validation (TXT)”. I tried disabling/enabling Universal SSL with not any success.

For now I have unproxied the website from CF but I would like to know why this error keeps comming up.

I have other websites in the same server with same SSL options on both server and CF side and there is no error.

Regards! :slight_smile:

This would be the error you get when Cloudflare doesn’t have any valid SSL cert to serve/use, which makes sense because the Universal is pending.

What’s the domain?
