 * I have a site which is under CloudFlare.
    This site is forced to be in HTTPS 
   only mode by a CloudFlare’s rule which redirects http to https.
 * I receive the following error when running the BackWPup job:
    The HTTP response
   test get an error “error:14077410:SSL routines:SSL23_GET_SERVER_HELLO:sslv3 alert
   handshake failure”
 * Plugin BackWPup disable SSL connection verifying v 0.1 is activated as well.
 * No error and job is done when running in http mode.
 * BackWPup is v. 3.1.4

 * Did you have as this question CloudFlare? BackWPup does only the wordpress standard
   things.

 * I know this is an old thread, but it’s currently one of the first search results
   for the SSL23_GET_SERVER_HELLO error message.
 * For the benefit of others who stumble on this in the future, I had the same problem.
   It’s caused because Cloudflare tries to force servers to a high level of security
   that’s not supported by your webhost for outgoing connections. Specifically, 
   outgoing connections from your server don’t support TLS, but only SSLv3.
 * Normally, updating CURL and OpenSSL will fix the problem. Specifically, CURL 
   7.39 or later, and OpenSSL 1.0.1c or later will support TLSv1.1 and TLSv1.2

 * For one site I have, it doesn’t work simultaneously with CF Flexible SSL Enabled.
   
   Lucky me, the active one I have works perfectly. Now I use on it
 * **cURL version** 7.36.0
    **cURL SSL version** OpenSSL/1.0.1e
