Hello. I'm new to this.
A few days ago, I installed Proxmox VE on my PC, and everything was running fine until last night when I discovered that the host machine could no longer access the internet. However, all virtual machines are functioning properly and can access the internet without any issues. So, after backing up all the virtual machines, I reinstalled Proxmox VE, but the host machine still couldn't access the internet. This PC is connected via 2 Ethernet cables to my TPLink router, which is in bridge mode. Usually, when my computer or phone reconnects to WiFi, the IP address tends to change frequently.
I have tried:
Any ideas?
PLEASE HELP! I can't even install zsh on the host now.

I have tried:
- Unplug one Ethernet cable, diable enp1s0/enp2s0
- Reinstall Proxmox
- Restart router
- Change IP in /etc/network/interfaces
- Reboot
Any ideas?
