Plesk key update deferral notification

Written by Mike on November 5, 2008 – 5:07 pm -

ERROR:

You getting emails from Plesk, or getting Following error while pressing “Retrieve Keys” from Plesk >> Server >> License Management

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


SOLUTION:

Plesk connects Parallels license server at 5224 port for the license update procedure. Make sure that the outgoing connection to ka.swsoft.com:5224 is not blocked on Plesk server or somewhere in the net. This can be examined with commands:

# nmap -P0 -p5224 ka.swsoft.com

[root@support ~]# nmap -P0 -p5224 ka.swsoft.com

Starting nmap 3.70 ( http://www.insecure.org/nmap/ ) at 2008-11-05 10:00 EST
Interesting ports on ka.parallels.com (64.131.90.38):

    I found that another possible cause of this problem is corrupted database entries in the admin database. The detailed my fixes here: http://blog.halomede.com/2008/11/plesk-license-auto-renewal-failures.html
