3CX failed to establish a TCP connection to activate.3cx.com - Version 18.0.7.441

[osc2021]

We are getting the failed to establish TCP connection & we cannot update because it says our license has expired today. We had renewed a month ago. We also have excplicit allow rules in place to activate.3cx.com

The issue is that the version can not reach our activation servers to see the renewed subscription.

Only the latest supported version of update 8 build 939 can be active, and since your version is lower, this is what is causing the issue.

We are the partner for the client. For some reason our account opened up incorrectly to post on the forum here.

What are our options to update it to the latest?
