Oracle free + cleavr + Cloudflare SSL not working

Hello. Before i open a ticket here I already searched on forum and find the same issues.
I am using a free oracle server and free cloudflare account.
I followed this tutorial 3 times: SSL - Cleavr docs
I already opened the 80, 443 port on List Security on Oracle Instance.
None of them works.

I have an UpCloud server with cleavr and ssl is working.
The problem maybe is with Oracle.
The website I am trying is:

Error 523

Ray ID: 709bad8cbe6997a9 • 2022-05-11 14:41:52 UTC

Origin is unreachable

If i type WWW on browser → I got this error: usa um protocolo incompatível.


The client and server do not support a common version of the SSL protocol or an encryption suite.

Thanks, amiedema to solve it!
