Symptoms

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

or

Couldn't resolve host name

or

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

Cause

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

Resolution

On December 1, 2014, the IP address of the license server was changed to 195.214.233.80 (IPv4) and 2001:67c:730::80 (IPv6). Make sure that the hostname ka.odin.com resolves to the proper IP from your server:

# nslookup ka.odin.com
Address: 195.214.233.80

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

If any of these servers are behind a firewall and old IP addresses of Key Administrator are listed in the firewall rules, please add new IP addresses of Key Administrator to the firewall rules to allow your servers to connect to ka.odin.com. This can be checked with these commands, depending on your OS:


Linux:

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

Windows:

telnet ka.odin.com 5224

tracert ka.odin.com

Note: Telnet Client should be installed additionally for Windows -> how to install Telnet Client

If you are using the APF firewall, check /etc/apf/allow_hosts.rules for the mentioned IPs or the hostname ka.odin.com.
