  • Resolved klusaki



    I want to use latest jetpack on my wp powered blog – http://kł
    The problem is its IDN domain and I’ve got error trying to connect to

    Error Details: The Jetpack server was unable to communicate with your site [IXR -32300: transport error: http_request_failed Couldn’t resolve host ‘kł’]

    is there some workaround to that problem?

    best regards,

    I think you are right and it may be the IDN portion and perhaps WordPress.COM dislikes processing http://kł

    I’ve no idea why. 😉

    If you are up to it and as an experiment, can you substitute your WordPress Address (URL) and Site Address (URL) from


    to read

    This is the ASCII version that I retrieved via

    You can do this on a temporary basis for testing by making a backup copy of your wp-config.php file (call it wp-config-SAVE.php`) and in the original file add these two lines.


    That way if anything goes wrong then all you have to do it restore the saved backup copy of wp-config.php.

    Let us know if you are willing to try that and if that works.

    thanks for the replay
    as you suggested, the punycode version works just fine 🙂

    it does not affect the site usage in any way

    Jan Dembowski, thanks for the tip! You’re right: we currently don’t support the Unicode representation of IDNs. We should 🙂

    We’ll working on supporting them. For now, though, ASCII is the way to go.

    I’m having the same problem on a new .org site. I’ve run Jetpack with no problem on other subdomains of mine, on the same host. The only difference I can see is that the subdomain name contains a number:

    Do I need to escape the 2 or something?

    ADDED: Never mind, it resolved on its own. The subdomain apparently took longer than usual to register. 🙂
