Phone System Went Down

[sandyhardi]

Received report that calls were not going through and web client or deskphones registration are down.

Tried to access web management console but unable to, getting "Server Error".

No network maintenance and upon checking AWS server is up.

This is the log when trying to access the server via console, by this time the phones and the webpages is still down.



And then we issued the command sudo systemctl restart 3CX* after which the services are up. We need help to find the root cause, because from the log we can't see anything except this log from 3cx management console.

Did you get an email to state an updated had failed?

check /var/log

generate a support info file and check that over too.

Hello, we didn't receive an email regarding update because automatic update is not enabled, we only received email regarding 3CXPhoneSystemMC01.

What's the possible root cause that we can check so we can replicate the issue and capture them with support info file?

You will need to enable verbose logging and generate the support file after the event do not post your support file here.

What you need to do first Is upgrade your PBX to version 20.
