Licensing Server Unreachable - No Firewall/Network Problem

    For a couple of days our Plesk-Installation complains about 'Unable to connect with licensing server'.

    This is NOT a problem with the connectivity to the licensing kerver ka.swsoft.som (ka.paralells.com).

    It is possible to
    - ping this server
    - make a telnet connection to port ka.swsoft.com:5224 therefore our firewall allows the traffic

    Further investigation with tcpdump/ethereal shows that when trying to retrieve the key from the control panel NO connection is initiated to ka.swsoft.com:5224.

    In /usr/local/psa/admin/logs/httpsd_error_log the following is logged

    Activation request for 'sapp-PPWSE-1' added
    Curl failed: unsupported protocol
    Remote call failed
    Connection error #-504: Network errorKey update performed at Wed Nov 26 11:51:56 2008
    result: Temporary error
    Licensing Server Unreachable: Unable to connect with licensing server.
    Please make sure that your network allows communication to ka.swsoft.com:5224.
    For more details check system help pages.

    Seems like a problem with curl.

    Curl is installed -> Output from rpm-qa | grep "curl" follows


    Our System is a SuSE Linex Enterprise Server 10 64bit (

    Our Paralells Sales Representative only offererd us some "Software training" to learn how to use software in a proper way - not very helpful

    Any help would be highly appreciated.

    Thanks in advance



    We tried the same on a different Plesk-Installation. Same Server-Plattform, OS version, Curl Version, Apache & PHP, but Plesk 8.2 and not 8.3
