Solved Missing Update on PBX

[AWS2P]

Hi,
on AWS lightsail VM i have a v20 PBX stuck to U3 and it's saying proudly is up to date, obviously is not.
There's nothing available in update menu.

Pbx is in automatic update mode. The pbx has been installed since only few months with Deb 12 iso
What can be done or checked ?
is there a SSH forced update command to push the U4 ?

Hi, is it resolving downloads-global.3cx.com ? check it has google dns, and then start a packet capture, open a second windows in your browser and go to the updates menu.

You should see if it is resolving correctly and the interaction with the server, that is the first point where you should start looking

Hi @Alejandro_3CX

Thanks for your answer, I checked resolution of downloads-global.3cx.com ----> OK
For Google DNS on a AWS lightsail not sure where to look and if it's a setting i can modify (may be i'm wrong)
Capture from PBX return that:

With Alphabetic help , i got it working, now U4 is running and i can see U5 alpha in update menu.
just did some ssh commands and then a Vm reboot .

All seems fine now

Big thanks to all who helped to solve.
