I have a Proxmox VE and I'm running 5 vm's recently my internet liked to cut out and I cannot access the server and then later found out that the server is the cause but i dont know whats in the server or my router that would be causing this. The internet would just no longer work on any device but as soon as its disconnected the internet comes back. If anyone knows any way to fix this it would be great! I liked being able to use the server

everything looks good, please post config for any VM.

Bash:
qm config <VMID>

and run journalctl -f command in your node, then start all VMs and see if there any network error
 
Whenever I try qm config <VMID> all i get is this
Configuration file 'nodes/cam/qemu-server/105.conf' does not exist
 
Please try to see the config file for VM if exist on this path:

Code:
ls -la /etc/pve/nodes/cam/qemu-server/105.conf


if exist please post output of this command:

Code:
cat /etc/pve/nodes/cam/qemu-server/105.conf
 
I am having same problem, I think. I am not using server level hardware. I don't know if that has any effects. I am using asus motherboard.

Here are some screenshot to check commands I have run which was ask by @Moayad

@Xudros Since you said there are 5 VMs running, I guess VMID 105 is not there yet? You better just type
Code:
ls -ahl /etc/pve/nodes/*/qemu-server/*
and check the result.
 
@eoinkim Yes, you are right, I changed to correct in file and it is working as it should be. Funny thing is when I log in to my router, that what it shows, but I changed to 192.168.1.1 and it worked. Thanks.
 
@ZooKeeper Your router has its gateway, probably, a WAN router somewhere (not in your house). And your router will serve as a gateway for your server. Hope this makes sense.
