The 3CX management console hangs uncontrollably.

[leyanu]

Hello People,

I have been having issues with the management console as it hangs uncontrollably. I use a windows device and this happens even on my mobile browser. My laptop has a 32GB ram and the mobile phone here is a OnePlus 6 so memory is not also an issue with the devices I use to access my console.

I need help here. I have moved from v16 to v18 thinking it was the issue. However, that didn't fix the issue. This is also my production environment so I need to fix this urgently.

Thanks in anticipation.

What is the spec of the device your PBX is on?
Is it dedicated for 3CX only?
If it's a Windows machine are you able to use the mgmt console directly off the server?
what antivirus is on it? try disabling it?

- My 3CX is cloud hosted AWS m5.8xlarge, so it is a high performance instance.
- It is installed alone
- How do you mean off the server?
- there is no antivirus, just windows defender. I haven't tried disabling it

Have you tried giving the PBX a reboot?

If you've tried from another machine/browser and tried in incognito mode then you may have to backup and reinstall to see if the problem still exists.

I forgot to add that the mobile device does not have any antivirus installed.

I have reboot severally. I have had to reinstall recently and restore my backup but the issue also started before with the previous in-premise installation.

First off, what do you mean exactly by "hangs uncontrollably", do you get a specific error, does it not load, what do you experience exactly and how often does this happen?

Also, how did you deploy this machine, was it through 3CX's PBX Express? How many extensions are configured to it? Have you happened to check system resources usage during the time the issue occurs?

Is there any chance the same License Key and same FQDN is also being used on a different machine meaning that you are sometimes connecting to that one instead? When the issue occurs, try running an "nslookup FQDN" to check whether the IP your FQDN resolves to is different than that of the AWS instance, this might at least give you a clue.

[email protected]$ nslookup bxxxx.3cx.co.za
Server: 172.31.0.X
Address: 172.31.0.X#53

Non-authoritative answer:
Name: bXXXX.3cx.co.za
Address: 18.159.XX.XXX

Above is what I get when I do a Nslookup

- I installed via the install in cloud option in the keys management tab on the customer account management page
- 206 Extensions
- Resource usage is good. CPU usage is usually around 16-25% and ram is Usually around 3-5%
- When I say uncontrollably I mean that it hangs too frequently once I click a tab on the console say settings it takes long to respond and most times leads to the tab on the browser crashing. Then I have to exit and refresh.
- Yes they are in other installations but they are no longer active all powered off.

Due bear in mind that you should not use the same License Key on more than one machine unless running a 3CX Failover configuration. Since you already shut it down, I recommend booting the machine up without an internet connection and then uninstalling 3CX to avoid issues in the future.

Apart from CPU usage did you also check RAM and HD usage too?

The instant you run nslookup, where you facing the issue? If the issue were to be due to connecting to an entirely different machine the DNS query (nslookup) would only return the wrong Public IP during the time you are facing the issue, otherwise, it would simply return the correct IP.

I'll PM you shortly for more information.
