Unable to connect to SSL in android 4.4 with cloudflare but it works with LetsEncypt

I am using letsencrypt for my site SSL, it works well with android 4.4, but when I enable cloud flare SSL, it does not work anymore. bot of them have SSLV3.0 unsupported based on the SSLLabs.

in android 4.4, I get this problem :

W/System.err: Caused by: javax.net.ssl.SSLProtocolException: SSL handshake aborted: ssl=0xb7af1b08: Failure in SSL library, usually a protocol error
