Proxmox not Connecting to Router

[tristan.lambert.bp1@gmail]

Good morning!

I configured proxmox onto a micro PC, set a static IP for the server. I also assigned it the correct gateway for the router.


CURRENT SETUP:
-ethernet directly to the router in port 3.
-Server static IP: 192.168.1.100
-Gateway: 192.168.1.1
-Cable is good - tested and verified.


I was able to set up the server and log into it from a different desktop via "https://192.168.1.100:8006".


The server was shut off and disconnected. My modem and router were restarted. I went to connect the server again. I powered it on and plugged it into the router. It is not connecting to the router. There is no network connection from the Proxmox to the network. I'm sure it's a simple fix, but I'm new to setting up servers and backend networking. Any and all advice is welcome. I'm simply trying to get it back up and LEARN why it no longer can access my network so it doesn't happen again.

As always: what is the output of ip a and cat /etc/network/interfaces? As readable photo of the Proxmox host console will suffice.

EDIT: And also, what is the output of lspci -nnk?

There is a good chance that OP has Realtek based NIC,

Because the name of the bridge-ports starts with wlx, it looks like you (or the Proxmox installer) are trying to use a WiFi connection as a virtual bridge. This usually does not work and is not supported by Proxmox (although you might be manually able to setup a NAT via WiFi; search the forum). Please connect a physical cable between your Proxmox and the router and setup it properly (or reinstall). You might want to read the manual: https://pve.proxmox.com/pve-docs/pve-admin-guide.html#sysadmin_network_configuration
