I am trying to VNC into VMs. I've setup ports via Monitor on one VM and adding a line to the conf file in another. The problem I am having is I get a connection refused from my VNC client and when I check for the VNC ports on PVE I don't see any. Is there a service I need to start to get VNC working? Consoles work on the VMs..

I must not have explained myself well. I followed the Wiki link you posted. When I try to connect the VNC client fails. I added a vnc line to the VMs config file

Code: 
root@pve:/etc/pve/qemu-server# cat 100.conf
args: -vnc 0.0.0.0:100
balloon: 0
bios: ovmf
boot: order=scsi0
cores: 2

I don't see a listening port on the PVE server

Code: 
root@pve:/etc/pve/qemu-server# lsof -i -P -n | grep LISTEN

when I try to connect to port 100 with VNC client I get an error

It appears to me Proxmox is not opening the port.

part shows that it listens on port 6000, if it does not work, the error must be elsewhere, e.g. the network
 
If I used the correct IP address maybe it wouldn't have failed :-) Thanks for pointing this out. When I used <serverip>:6000 instead of <clientip>:6000 it worked. I'm trained..
