I have a 3CX VM that seems to be dropping its network connection at random times, in most cases less than 24 hours. Not sure where I can find anything to tell me when it fails. When it happens, I can't reach from the outside and it can not ping out. With a comment the network is unreachable. As soon as I reboot it works again. Currently the instance has vmbr0 and vmbr202 which is a trunked network port with multiple vlans. I have vmbr202 listed twice with a public vlan with an outside IP and a private vlan that feeds our office phones network. vmbr0 is dhcp on our office network, this is temporary as this is a test server about to go to production. All IPs are set in the VM's interfaces file. Can someone give me a starting point as to how to determine what the problem might be. I am just learning Proxmox.
