The license currently installed on this server is showing up as invalid to InterWorx Control Panel. This may be nothing more than a simple misconfiguration on your system, or the license could actually be invalid.
Before opening a support ticket please try the following:
Check your system time and verify that it is correct. Even if it is off by only a few minutes you should reset it to the correct time. The easiest way to do so is to run the following in a root shell:
service ntpd stop
service ntpd start
Make sure your firewall has port 2443 open both outbound and inbound. If it's not open then InterWorx Control Panel can't talk to the licensing server.
Run the following command from a root shell to re-sync your license after checking the system time:
After performing the above please refresh [the license error] page to see if the license is now valid.
Finally, if the license is still showing as invalid please open a support ticket with the company sold you your license. If you bought your license directly through the InterWorx website then please open a ticket with the InterWorx team directly.
