Philips hue bridge found but cannot connect

Configuration
1

I’m having trouble with HAOS connection to the Philips Hue Bridge that I have running in my house.

HAOS is running inside Proxmox as a VM, living on the IoT vlan, and the Hue Bridge is also there on the same vlan. HAOS can see it, even prompt me to configure it, but I end up with the following error:

Retrying setup: Error connecting to the Hue bridge at 192.168.107.40

I tried to curl the local IP and I get the following:

I also see the bridge on discovery.meethue.com as follows:

[{"id":"ecb5fafffe9840b2","internalipaddress":"192.168.107.40","port":443}]

What I noticed is that in the logs it tries to use port 80, but the discovery url reports port 443. :thinking:

Any thoughts on what might be causing this? I can control all my lights through the Philips Hue app and Google Assistant/Homekit.

Updates:

I think the problem is coming from Proxmox’s bridge NIC, so it’s either a configuration issue (most likely firewall/routing in this case) or HAOS doesn’t like bridged NICs. The way I have Proxmox set up, is that it has two IPs - a management network and an IOT network, and since you can only assign a single gateway to it, I think this is where the issue comes from.

Installed HAOS directly onto a mini PC I had laying around, and connected it straight to the switch on an IOT VLAN port, and it immediately picked up everything in the house, including the Philips Hue Bridges and configured them immediately.
