No, also the free version is getting the final update.

Yes, the licence key should be blurred.
 
@Dragan Djurdjevic on your network do you use a proxy server or firewall that inspects all traffic for antimalware etc?

Yes, it is test environment, but problem is the same in production as well.

Ok, thats infos we need to help. First you need to access your pbx by fqdn. Did the firewallcheck pass?

If I access by FQDN issue is the same. Firewall check is passed

And you should check your firewall regarding proxy, ssl inspection and so on.

In test environment we have firewall but without deep inspection. We passed Aplha, Beta 1 and Beta 2 and we blocked now. Otherwise in V18 we did not have any issue with update.
 
Unless the system was modified in some unexpected way, or the 3CX update manifest is being cached by a proxy, you should not really be seeing the older versions.

You can also get help from your 3CX Partner to investigate and see if any critical files were changed.

Can we confirm root cause of problem? Is there procedure to restore 3cx to previous version?

Yes, we have no fix public IP address. IP address is changed periodically by ISP.
Can you help me to solve problem?
 
I see a local IP address in the logs instead of the public IP address. ( 192.168.76.1 )

The requests are taking a long time to resolve. This suggests network or routing issues.



We can also see that the server has two local IP addresses:

And I see multiple local IP addresses on the same PBX.
I also notice IPv6 addresses, but 3CX doesn't seem to detect them (in the screenshot of your Dashboard, IPv6 shows as N/A).

2 local IP addresses are fine; we are using both of them. We do not use IPv6

This is not an IP replacement by the ISP.
There are two public IPs that keep switching constantly, as if you have two internet connections.
Are you configured in Load Balancer mode?

Yes, we have SD-WAN and use both providers.
 
The simplest solution:
Switch to the Cloud,

or back up your PBX, create a new VM, and restore your backup.
Avoid having two local IPs. Start by running your PBX with a single local IP.

Be sure to follow the network configuration recommendations.
I see in the Support Info that the Firewall Checker failed, which is not a good sign.

To configure a policy to ensure that 3CX is not affected by the SD-WAN, you can set up a specific routing or traffic policy on your SD-WAN appliance to bypass SD-WAN for all 3CX-related traffic. Here’s a general approach you can follow:


Ensure that your router configuration follows 3CX's guidelines.

These apply to on-premise installs only!

No, This is not recommended... trying to bypass a problem with manual operations only delays it and allows it to worsen over time.

It is not issue with firewall, because even I disable one ISP provider and firewall check would be passed, issue is the same.
