V16 - failed to establish a TCP connection to activate.3cx.com

[telnetnz]

Hi all,

We just succesfully renewed our license in 3cx portal but cannot be synchronized by our 3cx system, which still show expire date is 31/12/2022. We suspect the reason is the system is still on the old v16 system, which makes system cannot communicate with activate.3cx.com.

Most Engineers are in holiday now, it looks like we only can finished the upgrade in earlier 2023. Just wondering what will happen afer license expire and befre upgrade to V18? Will the system downgrade to free license only, or totally not working?

Thanks

There are many facts that you need to be aware of as the PBX will not only be downgraded but in case the PBX is not able to contact the activation server for more than 60 days the FQDN will be auto-released due to inactivity as it is also explained below:
• https://www.3cx.com/docs/fqdn-management-allocation/#h.k579ihol7ovb
The update to V18 must be implemented as soon as possible using the latest 3CX ISO or Windows Installer to avoid this situation.
It would be also good to consider moving to 3CX Hosted as in this case the PBX will always remain up to date.
