Issues with new hub

So I’ve been trying not to leave SmartThings. Been rocking the ST 1st gen hub since release. Tried the latest and greatest and after loosing a bunch of my devices I had collected solutions for previously I decided to give Hubitat a try.

Can’t seem to get past the
“Portal dot Hubitat dot com” bit

Network is Ubiquiti from end to end save the one dumb gigabit switch in the rack for things that don’t play well with POE, tool doesn’t find it via Standard or advanced discovery , hub doesn’t seem to be pulling an IP on the network, so shows blank in the router tables in the ip field. Very strange.

Plugged the hub into the dumb gigabit switch in the rack. The Hub’s light went from blue to green when I plugged it in in place of my newer smart things hub. I have not unplugged or power cycled it since initial plug in.

I’ve tried chrome, brave, and safari browsers on macs both wired into the same switch, as well as via WiFi on the same network and vlan. Also not working via edge or IE on a borrowed windows laptop with a clean windows install.

Not sure at this point if I have a bum new hub, or if my network is smacking down whatever the site is trying to do within my network to locate the hub.

The network is fleshed out beyond most average home networks but shouldn’t be a problem for anything that can plug into an Ethernet port and properly request an ip.

basic question, but do you have your switch profile set correctly for the port? is the DHCP range large enough for the subnet you're adding it to? does that subnet have free DHCP addresses?

Uplink to the non managed switch is good. I can ping all my Sonos units that are plugged into the same switch. Plugged in a Mac mini server to test the port the hub was using and it pulls IP with no issue via DHCP, I can remote into it and it shows no connectivity issues. DHCP has plenty of room available in the pool. And lease times are reasonable given the little turnover on the network.

Are you using a full Ubiquiti solution with their security gateway or UDM/ UDM Pro or your own router? If you go into your router do you see the mac address of the new device and it's IP address? Just want to confirm that your router is getting the bid for DHCP from your Hubitat.

Are you using any VLAN's or 3rd party DNS or mDNS services that are non standard? What I found I had to do on my Ubiquiti network was for initial setup use the default VLAN (1) for discovery to work. Also I had to plug my laptop into that default VLAN. I use a Untangle router as my firewall/router since my PC and Phone devices are on a secure VLAN and according to the Hubitat documentation the devices have to be on the same segment for the processes to work.

Is it a 255.255.255.0 subnet?

Your computer needs to be on the same subnet / vlan for portal to find your hub.. Otherwise you can get the IP of the hub from your Ubiquiti gear..

Did you purchase your hub from Hubitat? Or a third party reseller?

If it is the latter, there’s a possibility that it was previously used and configured with a static IP. As a consequence, the platform loads just fine (green LED), but it cannot be reached on your LAN.

The fix, if you think the hub is Static IP and you don’t have access, is to reset to DHCP. This works as long as the hub platform isn’t too old (as might be the case from a third party seller). Button is on the bottom. Instructions are here.

my.hubitat.com will have advanced tools to get to the hub by MAC address too. if reset to DHCP setting isn’t working.

I run the UniFi Gateway, several UniFi managed switches, UniFi APs, and Security cameras. Anything plugged into the network anywhere in the home or on the WiFi is on the default VLAN until I manually assign it otherwise typically only for basic QOS rules relating to VOIP or security cam traffic being prioritized over bulk media packets. DNS is handled by google, only after referencing local DNS entries.

In other news the HUB is up, changed out the network cable that came in the box to a known good one and it started acting right, pulled an IP, and was nearly immediately found without and advanced discovery fiddling required.
