1 - use 8.8.8.8 DNS
2- disabled IPV6
3- uninstall and reinstall again from a backup
And am already can ping to activate.3cx.com also i can telnet on it by 443 port

Hi @MrUn1x

Regarding your issue please try the below and see if that fixes the issue. In the Management Console navigate to Settings >> License >> Edit and confirm that the following fields have values, Company Name, and Country. If not, please fill them in and click on OK and then click on Refresh License Key Information.



Hi @f.schulz

Regarding your issue, please note that installing the PBX on a raspberry pi is no longer supported. Additionally, the raspberry pi only supports up to Version 18.0 update 2, which cannot reach the activation server. Only versions 18.0 update 5 and above are able to reach the activation server. In this case, you will need to take a full backup, uninstall and reinstall the PBX on a supported OS.

Hello @NikolasA_3CX

Hello,

we have the same problem with the activation. Our Licence expired but has been renewed and since then the 3cx says that the connection to activate.3cx.com connot be established. I tried to update the system via mangement console and it says that the maintenance is expired and that the update is not available. From the server i can ping activate.3cx.com and it is working without any problem but the PBX does not find the way to activate.3cx.com! I have read trough the forum and if the only solution is to uninstall and reinstall the whole system, then sorry 3CX this is ridiculous! If we miss to update the system before the licence expires and as result get such trouble to get the licence back working this is simply unacceptable. I hope you have a solution for this problem without the uninstall/reinstall process because we have now a running system being degraded (with a paid licence) and a company not able to function properly!

Rgds,

PBX version? You need at least V18 U5.

Hello,
The version on the server is 18.0 Update5(Build 481) and on our customer portal, it is 18.0 Update 4 (Built 461).
Issues came after the upgrade from update 4 to update 5.

Attached screenshots of both.
Thanks.
