Symptoms

Licensing Server Unreachable: Unable to connect with licensing server.
Please make sure that your network allows communication to ka.parallels.com:5224.
For more details check system help pages.

or

Couldn't resolve host name

or

Can't connect to ka.parallels.com:5224 (Timeout)

Cause

The Parallels product tries to connect to the license server ka.parallels.com at port 5224 to update the license, but it cannot establish a connection.

Resolution

Since December 19, 2011, the IP address of the license server has changed to 77.245.23.80. Make sure that the hostname ka.parallels.com resolves to the IP 77.245.23.80 from your server:

# nslookup ka.parallels.com
Address: 77.245.23.80

If the license server does not resolve to the correct IP, check the /etc/hosts file.

Also make sure that the outgoing connection to ka.parallels.com:5224 is not firewalled on your server or somewhere in your network. If this is the case, you can contact your ISP to open the port. This can be checked with these commands:

# nmap -P0 -p5224 ka.parallels.com
# telnet ka.parallels.com 5224
# traceroute ka.parallels.com

If you are using the APF firewall, check /etc/apf/allow_hosts.rules for the IP 77.245.23.80 or the hostname ka.parallels.com.
