I pulled my brand new HA Green from the box, plugged in ethernet then power… and I can’t connect from browser via homeassistant.local:8123 or homeassistant.local:4357.
I connected to my router and found homeassistant in the DHCP lease table, and can’t connect via 172.16.16.28:8123.
From a cmd prompt, homeassistant.local resolves to 172.16.16.28, but I’m unable to ping 172.16.16.28.
When attempting to connect via Android app, the app sees 172.16.16.28 as a server, but it’s unable to connect.
I connected a monitor/keyboard. The last line says “System is ready! Use browser or app to configure.”
Looking at ‘ha network info’ I see the same IP info and the status is connected.
Any ideas?
Also… my laptop is on the same network as the HA Green device (ip = 172.16.16.24). Same subnet mask (/24), same gateway (172.16.16.1)
Following up… i was able to successfully update the os to version 17.0 - confirming internet connectivity. Watching the system boot, I didnt see any errors. My phone app sees the server when it scans the network, but can’t connect to it.
Hi, have you only tried with your mobile device?
With the companion app you first have to add the SSID from your WiFi network.
I’ve also tried connecting via a browser on a laptop - both http://homeassistant.local:8123 and the ip address (http://172.16.16.28:8123).
Regardless, how would I add the SSID for my WiFi network? My mobile is connected via WiFi, but the HA Green is connected to the same network via ethernet. When launching the HA Android App, sees the server. When I click on it to connect, it times out.
On your laptop, ping the HA IP address
In the mobile app settings, you have to add the WiFi SSID.
But first make sure you can access your HA from a browser.
Make sure your WiFi is not configured as a Guest network, with segregation or as a private VLAN or similar.
I’m unable to ping the HA IP address (172.16.16.28) from my WiFi connected laptop with IP 172.16.16.24.
I was able to update the HA to version 17.0, so I know it’s connected to the internet.
If the HA is supposed to respond to a ping, I will check logs on my firewall for clues.
So if you have no connection from your laptop/to to your HA, nothing will work.
Your laptop has 172.16.16.24
Your HA has 172.16.16.28
Without knowing the subnet mask, this seems to be the same logical network.
Are those addresses handed out by your router and still active?
Is your laptop running Windows?
What kind of network is it in, as Wally already touched: Guest/Private/Public?
Both subnets are /24. Addresses are both provided by DHCP on firewall.
Laptop is running Win11. There is only one network.
I can troubleshoot the network and circle back later today.
The fact that the mobile app discovered HA but couldn’t connect made me think initial connectivity was ok.
If the HA should respond to ping, I’ll make sure that gets resolved.
Thanks for your help. I’ll be in touch.
That’s your starting point: making sure that you can ping your HA.

Update - I attached my laptop via ethernet to another available port on the same firewall that the HA was plugged into, and was still unable to ping the HA.
I brought the HA to my office and everything worked perfectly.
I have owned an IT Managed Service Provider for 27 years… When I explained this problem to one of my nerds he said “it sounds like your firewall needs rules for LAN-to-LAN and LAN-to-WiFi.”
My nerd has added those rules, and I expect everything will work when I get home tonight.
Thanks for everyone’s assistance with the troubleshoot process.

That means you did run a guest network, use segreagation or have setup VLANs.
