Unable to Renew License for Self-Hosted 3CX Instance via WebGUI

[MarioC]

Hello everyone,

I recently renewed the license for my self-hosted 3CX instance, but I am encountering an issue when trying to renew the license through the web GUI. The following error message appears:

"Unable to reach the 3CX Activation Server. Please check that your primary DNS server is able to resolve activate.3cx.com."

Despite this, I have thoroughly checked the connectivity and the reachability of the domain from the PBX. Everything seems to be in order, and the domain resolves correctly.

Details:

• 3CX Version: 18, Update 9, Build 31

Has anyone else experienced this issue or have any suggestions on how to resolve it?

Thank you for your help!

What is the DNS server you currently use? Change it to use googles.
