Hub Disappeared

Oh man! I was making a ton of progress, learned the RM and drivers, etc. Anyway, moving over from Wink, I had one last device to add - an Inovelli 2 channel plug-in module. I added the driver, then excluded the plug, then got it added. That's when the hub became unresponsive.

I can get to the hub with a browser now. The portal doesn't discover it, I tried using the mac address too. I tried switching ports on my switch. Nothing.

The light on the hub is solid green. Not sure what to do now...

Can you get to http://hub-ip:8081? Or can you ping your hubs IP? If not either of these than I'm guessing your hub's IP changed, did you set a DHCP reservation for your hub in your router to keep it's IP always the same?

I can not reach http://hub-ip:8081/

I also did not set a reserve DHCP. I'm assuming that's something I need to do... but right now I can't even find the hub on my network...

Does this show up your hubs IP address?

Logon to your router and look at the DHCP table you should then be able to find your hub by it's MAC address which should be listed on the bottom of the hub. Then mark that MAC IP combo as reserved/static and use that IP going forward.

Do you have any computer on your network that you can use the "arp" command from (like a Mac or an RPi)?

Do "arp -an | grep 34:e1:d1" - that will indicate the IP addresses of your Hub. At least both my C5 hubs have MAC addresses that start with 34:e1:d1.

Edit:
This is what the output looks like:

odroid@odroid : ~ $ arp -an | grep 34:e1:d1
? (192.168.1.46) at 34:e1:d1 :80:xx:xx [ether] on eth0
? (192.168.1.36) at 34:e1:d1 :80:xx:xx [ether] on eth0

@bobbles it shows it under "My hubs". BUt nothing shows up when I go to "find hubs."

@Terk I am using Eero, which actually makes it very easy to reserve the IP. I did that, still nothing .

If you still have issues, I would contact support@hubitat.com

Any easy way to interrogate your network is with Fing as well. Much better than what I have seen available in most consumer routers.

Available on both Android and iOS.

So are you saying you can see your hub like this. (Find hubs).

Does it not show the IP address underneath the name of the hub. (If you can see it of course).
But nothing under hub list.

@bobbles yes it does show IP address.

Ddi that, but I only get results when I do arp -an

And when you use that ip address can you see your hubs devices/apps etc?

@bobbles no

I would suggest support should be your next step then.
@bobbyD

After you reserved the IP you may need to reboot the hub to get it to switch if it was on another IP. Did the euro show what the IP was or did you just assign an IP to the MAC?

Have you tried to ping the IP address? I would not reboot/restart the hub until you contact support.

Talked with @bobbyD in support. No idea how this happened... but I'm back.

TL;dr - both the hub and my laptop were hardwired through the same unmanaged switch. When I went to pair my last device, I unplugged my laptop and went wifi only. When I plugged back, I couldn't get connected to the hub. So, I unplugged the ethernet from my laptop and everything came back up.

The weird thing is I plugged ethernet back into my laptop (no wifi), and everything is working great.

Thanks all!
