Cannot log into Proxmox web interface

[alphadog]

Fresh install of Proxmox v1.9 on an Asus KGPE-D16. There are two LAN connectors; the board has an Intel 82574L controller. I am connected to the LAN1 connector which is also eth0.

Here's /etc/network/interfaces:

auto lo
iface lo inet loopback
iface eth0 inet manual
iface eth1 inet manual
auto vmbr0
iface  vmbr0 inet static
     address 192.168.1.3
     netmask 255.255.255.0
     gateway 192.168.1.1
     bridge_ports eth0
     bridge_stp off
     bridge_fd 0

Trying to connect from another computer to https://192.168.1.3 does not respond. Pinging 192.168.1.3 does not respond.

Where do I start looking/troubleshooting?

Thanks.

You already tried to plug the cable into the other slot?

You can also try to use tcpdump to see whats going wrong.

Yeah, wouldn't you know it. The controller provides two jacks, and one seems to have intermittent issues. I can ping out, but with heavy packet loss.
