    Sorry for my bad english.

    After installing the plugin Google Cloud Print i get this error on the Licence Page:

    Error: WP Error: cURL error 35: error:1407742E:SSL routines:SSL23_GET_SERVER_HELLO:tlsv1 alert protocol version

    Thanks for your help!

    libcurl version

    did you also/already speak to your host about this ? this is a server/setup issue

    hmm, i know nothing about win servers really.
    however – though that’s just a wild stab in the dark – you could try the following
    (make a backup of the file you are editing – if it falls over revert to that backup)

    in the plugin you find the following file


    on approx line 49 you will find
    curl_setopt( $this->ch, CURLOPT_HTTPAUTH,CURLAUTH_ANY);
    right AFTER that ADD
    curl_setopt($this->ch, CURLOPT_CAINFO, ''.ABSPATH . WPINC . '/certificates/ca-bundle.crt');

    and save. let me know if that fixes it (or any other/different errors you might get)


    Thanks, but nothing changed. It’s the same problem.

    After check the “Activate Licence” an Save comes the problem red marked:

    Activate License License Status unknown
    Error: WP Error: cURL error 35: error:1407742E:SSL routines:SSL23_GET_SERVER_HELLO:tlsv1 alert protocol version

    try this line instead
    curl_setopt($this->ch, CURLOPT_SSLVERSION, 6);
    TLS lower than 1.2 is disabled on (for good reason)

    forget that. this would affect the cloudprint itself, not the license screen. that’s something completely different. I misunderstood.

    I’ll have to dig around a bit

    which version of wppizza and cloudrpint plugin are you using ?


    Ok. Don’t worry, its because of me, I dont tell you clearly the problem.

    It’s only the licence Screen. I use both of the newest versions.

    Cloudprint 4.0.1
    WPPizza 3.0.beta.170427.1

    I don’t know in this moment, if it’s only a Cloudprint Licence problem, or general licence problem with all Add Ons – Give me a little bit. I will check it and answer soon.

    PS from what i can see your open ssl version is 2 years old
    i would suggest you update this . (this *might* be the issue )

    also what does it say about “Remote post” here

    Admin & Mod

    PS: version 3 beta has been updated (although that has nothing to do with your issue, just mentioning it )


    Thanks a lot. I logged in to Plesk and changed the Version of PHP from 5 to 7.0.18, so OpenSSL runs in newest version, too.

    My problem is solved! THANKS A LOT!!! 🙂
