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): PORT STATE SERVICE 5224/tcp filtered unknown Nmap run completed -- 1 IP address (1 host up) scanned in 2.205 seconds
