Cannot connect to 3cx PBX

[nhall]

Hi, had new switches installed and we had to down the on premises 3cx server, now we cannot get to the 3cx pbx dashboard, also on the debian server we can ping itself but no phones, all the phones in the school say no service, no settings have been changed, any ideas would be truly grateful as we are dead in the water at present. Many thanks guys

Can you ping everything from the debian server i.e. firewall .If not then I would say you have networking issues somewhere

Hi, we cannot ping anything but itself, I know we have a network issue but just wondering if anyone has had this before when replacing a main core switch, Im new here so I have checked the vlans and they are all correct, so at a loss at mo. Im looking at reinstalling 3cx on a windows server as have a full 20g backup of the system. But i just dont understand why this has happened. We have even gone back to the old core (so basically back as if we didnt upgrade) and we replaced and plugged it in and its doing the same.

Check the 3cx server has the correct network settings, it has fixed IP and was not configured with dhcp as the IP address may have changed.

If you connect an unmanged switch to the 3CX server and connect a laptop to the same switch, do you get network traffic i.e. pings

check the 3cx services (stop / restart them)

Service 3CX* status | grep ".service -\|Active"

or

service 3CX* status

or

systemctl status 3CX*

service 3CX* stop (3CX* using star will stop, start, or restart all services starting with 3CX)
service 3CXCfgServ01 stop
service 3CXPhoneSystem01 stop
service 3CXSystemService01 stop
service 3CXEventNotificationManager stop
service 3CXQueueManager01 stop
service 3CXTunnel01 stop
service 3CXIVR01 stop
service 3CXMediaServer stop
service 3CXCfgServ01 stop
service 3CXPhoneSystemMC01 stop
service nginx stop

and with same logic services can be started or restarted with start and restart at the end

service 3CXCfgServ01 start
service 3CXPhoneSystem01 start
service 3CXSystemService01 start
service 3CXEventNotificationManager start
service 3CXQueueManager01 start
service 3CXTunnel01 start
service 3CXIVR01 start
service 3CXMediaServer start
service 3CXCfgServ01 start
service 3CXPhoneSystemMC01 start
service nginx start

Hi, we ran this and all services have started all nice and green, interestingly we cannot seem to activate the network nmtui, says cannot activate connection: activation failed, this is when we have the ipaddress i.e 192.168.140.2/24 with a gateway.
