The problem is caused by an invalid server host-name, specified in the following configuration files: hspc.conf, hspc.ini.


  1. Verify and set a valid server name in hspc.conf:

    ~# grep SERVER /etc/hspc/hspc.conf
    SERVER\_NAME     = plesk.hostname
    SERVER\_PORT     = 12443
  2. Where you see plesk.hostname in the examples, enter the full hostname of the Plesk:

    # MYSQL_PWD=`cat /etc/psa/.psa.shadow` mysql -u admin psa -e"select * from misc where param='FullHostName'"
    | param        | val            |
    | FullHostName | plesk.hostname |
  3. The hostname will be resolved to NNN.NNN.NNN.NNN. Post 12443 will be open for local connections:

    # telnet plesk.hostname 12443
    Trying NNN.NNN.NNN.NNN...
    Connected to plesk.hostname.
    Escape character is '^]'.
  4. Verify that the valid URL is set in hspc.ini:

    # cat /opt/plesk-billing/htdocs/lib-billing/include/config/hspc.ini
    URL = https://NNN.NNN.NNN.NNN:12443/HSPC/Plugin/SOAP/WebServices

NOTE: IP address may be specified instead of NNN.NNN.NNN.NNN in hspc.ini.
