i can't connect to activation.3cx.com

[pausu]

Hi,

We have a 3cx server mounted on a Hyper-V with windows server 2016.
On 7 April we forgot update on time and now we can't connect to the activation servers. Our license version is 15.5.15502.6

We tried to update with on of yours updater tool but it didn't do anything.
The DNS are configured as: 8.8.8.8 and 1.1.1.1 but it doesn't work

With an nslookup we can reach the activation server on: 151.80.125.88
On 3cx update service we can see a pending update: 15.5.20000.6 but we can't update because our license is expired. It just fish eating his own tail...

Can any one help us??

Thanks!

If maintenance has yet to expire for the License Key in question, why not upgrade directly to version 16?

All you would have to do is:

1. Take a full backup of your current 3CX PBX. Move it away from the machine.
2. Uninstall 3CX and Install the latest version.
3. Restore the backup during installation.
