Unable to upgrade to V18 Update 9B

[Dave Williams]

I have received emails from 3CX advising that I need to upgrade from V18 Update 9A to Update 9B

The webpage at https://www.3cx.com/blog/news/ssl-certificate-update-2025/ provides instructions on how to achieve this update, but they do not work.

When I visit the updates page on the management console I see the following info:

Release	New V18.0 Update 9 B	Out Of Date	18.0.9.31	18.0.9.35	Update for License Activation

[th width="100px"]

Type​

[/th][th width="240px"]

Name​

[/th][th width="100px"]

Status​

[/th][th width="140px"]

Installed Version​

[/th][th width="300px"]

Online Version​

[/th][th]

Description​

[/th]​

But it is not allowing me to initiate the update, presumably due to the 'out of date' status.

Can anyone advise how I can initiate this update by other means?

to late... The upgrade need to be done before 24.2.2025. Anyway, on the management console you just need to highlight the Update and press download. Now it could be possible that this wont work anymore, than you need to upgrade and restore.

Your only way forward now is to upgrade to Version 20.

Today we also tried the upgrade from V18.0 Update 9 to V18.0 Update 9B. The upgrade started but returned an exception. Here is the log:

Does it mean that the installer cannot establish the SSL connection for downloading the patch?
Manual download of https://downloads-global.3cx.com/downloads/v180/sp150/PatchX39_64.zip works fine.

The time limit for that was the 23rd. On the 24th the connection is no longer possible.
