    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

    The error mentioned above happes when I try to backup to DropBox

    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
