3CX Installation: Could not connect to 3cx Server

[tiranosauros13]

I am trying to test 3CX Debian Version on Oracle virtual machine
I download the Image and I set the network adapter to "bridged Adapter"
I Choose to configure manually my network settings durring installation so i give the settings bellow:

• IP: 192.168.1.3
• Gateway: 192.168.1.1
• Name Server: 8.8.8.8

IP is unique on network and DHCP range is 192.168.1.50-254
My router IP is 192.168.1.1
I Choose different name servers, even i try to leave it blank or use my Router as name server

Error:
Installation flaws normaly. I am creating partitions. After first reboot witch trying to connect on Internet error occurs.
"Could not connect to 3cx Server. Please check your Internet connection and try again."


Eventually I choose to left configuration on automatic and all works fine. Although I need to setup a static IP and I manage to configure it from Debian Terminal but this cause other issues like giving wrong IP on QR Codes.

Oracle VM Network Adapter Settings:

Looks like you just on't have internet when moving to static IP. What are your settings when you're in DHCP ?

Hi,

Debian's installer will need correct network configuration otherwise you will get this error if it cannot reach our servers to complete the installation.


Note: The environment you are using has not been tested and is not supported (use it only for testing - not production) so we do not know whether the virtual NIC or even the PBX will behave correctly after installation. Please check our supported VM Platforms here: https://www.3cx.com/docs/manual/phone-system-installation-windows/#h.5hoy5wwhhk5c

John thank you for the info. I didn't mention that Oracle Virtual Box isn't on that list. My mistake.
Although i believe that isn't issue of Virtual Machine because I let DHCP do the dirty work during installation and connection with 3CX Servers successfully completed.

On First time configuration my IP is one of DHCP game me:


Completing configuration


I change the IP through Debian terminal by artering /etc/networks/interphases with nano

and connecting again to Dashboard with new IP address


This seems good but i found a small issue. When I am creating a new extension. As you can see below the provisioning IP is 192.168.1.59 whitch is the dynamic IP that routers gave me.


I can choose 192..168.1.3 from drop down menu but i wouldn't prefer that. I am afraid of serious issues so i want finish installation correctly

In conclusion I am afraid that is not virtual network adapter issue but I will try with one of already tested VMs

Have you set the correct IP address under Settings page and also restarted Debian after changing IP settings?

I am not sure if i did it before. I did it now. The issue still occurs

I tried replicating the issue you have, while under a DHCP network and using static IP. If I use a free IP higher in the range it works, if I happen to use an IP that's already bound in the routers ARP table then I get the error message you also got (since debian cant reach the internet)

Since you changed the IP (under network settings -> Select Network Card Interface) to reflect the correct one, try restarting all the services or the VM to ensure the IP updates across the system.
