Solved Unable to reach 3CX License Activation Server.

[Kikoen]

Hi,

We've purchased a license, but cannot edit the license key in the 3CX Phone System Management Console.
The only clue we have is the error message:

Unable to reach 3CX License Activation Server. Confirm that your Primary DNS Server is able to resolve activation.3cx.com

However, I have tested DNS resolution from the commandline and it seems to work correctly.

; <<>> DiG 9.9.5-9+deb8u14-Debian <<>> activation.3cx.com

Does anybody know how to proceed with the activation?
Our PBX has version 15.5.6354.2 and is running on top of a Debian Linux.

Hello @Kikoen

Please note that the licence is bound to the FQDN during installation and only during installation.
That means that you cannot change the key without re-installing the PBX.
If you have a new key you wish to use you need to do the following:
Perform a backup without licence and FQDN. Save it to a non 3CX location
Un-install the system.
Release the current key from the FQDN if you wish to use the same FQDN by accessing https://customer.3cx.com .
Re-install the system using the backup you created. when asked provide the new key and the FQDN.
For future reference please note that keys are up-gradable meaning you can upgrade your current key to a higher version so you do not need to re-install the system.

OK, I've reinstalled the system and the license key has now been changed.
However, the PBX tells me activation has failed and I still get the message "Unable to reach 3CX License Activation Server. Confirm that your Primary DNS Server is able to resolve activation.3cx.com "
From the command-line activation.3cx.com resolves to 151.80.125.88 .

In that case please try using 8.8.8.8 as your primary DNS and try activating the licence again.

 

[Kikoen]

The license has been activated.
Thank you!
