After doing some random module updates that I usually find quick and easy my PBX seems to not be able to connect to the internet. I am not sure if this is just a coincidence but no network config has changed but now suddenly whenever i try to ‘search online’ for module updates the web control panel times out and then reloads to the dashboard. My external trunk connection has also dropped as the PBX is unable to communicate externally to the voip provider.
Also if i try to check for updates in System Admin i get this error: fopen(http://upgrades.schmoozecom.net/updates.php): failed to open stream: Connection timed out
System admin shows i am currently running version: 10.13.66-20
Hi my only suggestion is to check your DNS settings under System Admin - DNS to see if it is correct.
I can confirm DNS is working by SSH into shell and ping upgrades.schmoozecom.net.
My system is working including module upgrade, however I am having the same problem as you are with system admin upgrades. Getting the same error as you are.

Turns out our issue was to do with a firewall changed that had happened almost at the same time. Caused all traffic to be blocked from our PBX. Typical timing.
