Initially it was working fine. I used Flexible certificate. But after I experimented with Lets Encrypt Certificates within my website hosting provider Infinityfree, and disabled this certificate, and reverted back to Cloudflare Flexible certificate, but for some reason Cloudflare was still “redirecting” my https request and showing Let’s Encrypt Certificate, despite they were removed from my hosting provider. I deleted my domain account with Cloudflare and setup Flexible certificate again, its active but now, and it does not use Let’s Encrypt Certificate but instead, cannot use any. For my https requests I am getting the following error indicating there is no SSL connection
This site can’t provide a secure connection
sent an invalid response.
I believe like Cloudflare caches in somehow the previous settings, I tried to clear also my browser, also use different browsers, clear caches at the Cloudflare, but I cannot get Flexible Certificate sorted. I tried to disable the universal certificate, and then reissue the certificate, it does not help too. When connecting over http protocol I can connect to my website, since Flexible certificate uses http to connect to the hosting provider, it does not work without any issue regardless whether there was Lets Encrypt certificate before installed on the website hosting server.
