[CLOSED] Need help reconnecting to Home Assistant after IP address disappeared | Home Assistant | Page 1

I'm running HA on a KVM virtual machine on Ubuntu. Recently my computer lost power and the VM ran fine, but I couldn't connect to HA through my browser. In the VM console I saw that there was no IP address assigned. I found this discussion that gave me a place to start https://community.home-assistant.io/t/no-ip-address-showing/290149/42. I tried binding the MAC to the IP in my router settings and using the command 'network update enp1s0 --ipv4-address x.x.x.x/24 --ipv4-gateway x.x.x.x --ipv4-method static' which did populate the IP address and gateway, but I'm still not able to connect in my browser. I used the same IP address I bounded in the router settings. I used the gateway address listed on my TPLink Router webpage under Advanced -> Internet -> Default Gateway, but 'm not sure if that's correct. Any thoughts on what to troubleshoot next?

#

Here's the current ouput on my VM https://imgur.com/a/voVOpQU

#

If you "bind" a ip address in the router you probably want DHCP/auto.

#

That gateway and ip combo look very weird. What ip does the device have that you try to visit HA from?
Where is the VM run off of? What ip does this machine have?

mossy magnet May 17, 2024, 7:35 PM

#

Thanks for your reply @idle adder it's taken me a while to come back to this project. I will remove the 'bind' and look for the IP of my machine vs. the virtual machine. I am running KVM on Ubuntu.

mossy magnet May 17, 2024, 9:33 PM

Okay I have 2 IP address for my machine.
Wired: 192.168.0.184

The configuration for my bridge br0 is

network:

    enx00e04c36808c:
      dhcp4: false

Why wireless for a server?

#

Not that familiar with netplan.

mossy magnet May 17, 2024, 9:34 PM

I'm using the wired connection for my bridge

The NIC itself should not have a ip but the bridge that's using it.

mossy magnet May 17, 2024, 9:35 PM

#

So far it's still showing no IP address after switching back to auto

mossy magnet May 17, 2024, 9:38 PM

#

idle adder The NIC itself should not have a ip but the bridge that's using it.

I'm not sure what that means. Does that imply that my configuration is set up incorrectly?

idle adder May 17, 2024, 9:38 PM

#

I'd say so.

#

Unfortunately I'm not familiar with netplan or plain KVM/libvirt. I use the interfaces file on proxmox.

#

I checked the netplan docs and your config seems okay. Maybe something else is interfering.

mossy magnet May 17, 2024, 9:44 PM

#

I am not either 😢 I'm reviewing the directions I used to set up originally, and it said to use the IP address of the ethernet connection that comes up in 'ifconfig -a', which I think from my output is

enx00e04c36808c: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.0.184  netmask 255.255.255.0  broadcast 192.168.0.255
        inet6 fe80::fdeb:582f:37f0:c208  prefixlen 64  scopeid 0x20<link>
        ether 00:e0:4c:36:80:8c  txqueuelen 1000  (Ethernet)
        RX packets 118706  bytes 105237844 (105.2 MB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 64750  bytes 10378429 (10.3 MB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

which seems to have the correct matching IP address used in the config file of 192.168.0.184

mossy magnet May 17, 2024, 9:44 PM

#

idle adder I checked the netplan docs and your config seems okay. Maybe something else is i...

thanks for checking

#

I wonder if I should just try setting the static IP address for HA again, but this time with the correct gateway

idle adder May 17, 2024, 9:44 PM

#

I'd check /etc/network/interfaces, systemd networking, networkmanager and libvirt configs.

#

I don't have the environment to test netplan and stuff like this right now.

#

I can recomment you to use Proxmox VE if you want a more pain free hypervisor solution.

#

Are you using ubuntu desktop?

mossy magnet May 17, 2024, 9:47 PM

#

there's no interfaces file in etc/network not sure if that's related to netplan. I am using Ubuntu installed on an old macbook air

#

Ubuntu 22.04.4 LTS

idle adder May 17, 2024, 9:48 PM

#

Desktop or server?

mossy magnet May 17, 2024, 9:48 PM

#

desktop

idle adder May 17, 2024, 9:48 PM

#

The interfaces file is pretty much on every OS as far as I know.

mossy magnet May 17, 2024, 9:48 PM

#

I think, I'm using an old laptop

idle adder May 17, 2024, 9:48 PM

#

I'm asking because the desktop might interfere as well.

#

I'd recommend you configure the bridge with the GUI in this case.

mossy magnet May 17, 2024, 9:49 PM

#

okay, that's fair. I haven't used Proxmox VE before but I can learn.

#

(assuming that's what you are referring to re: GUI)

#

Okay it's downloading, do you have any suggested references to get started with proxmox ve for this application?

idle adder May 17, 2024, 9:56 PM

#

No I meant the ubuntu GUI as in desktop.

#

Yeah hold on.

They're quite good.

Awesome, thank you for the suggestion. I'll get started there and come back when I have updates.

Hi @idle adder, I’ve run into some issues installing ProxMox that I’ve stalled out on. Wondering if you have any ideas.

I created a bootable usb with ventoy and installed proxmox, but when I try to reboot it gets stuck. I’m running Ubuntu on an old MacBook Air. Here are some videos of the behavior.

#

Screen where I get stuck rebooting after installation of ProxMox from USB Drive

#

Dang, for some reason discord isn’t letting me post pictures or videos

#

Now whenever I try to restart, I get a black screen with ‘Booting ‘Proxmox VE GNU/Linux’. Loading Linux 6.8.4-2-over … Loading initial ramdisk … and then nothing happens

Oh right, thank you for the reminder @idle adder! I tried to upload last weekend but Imgur crashed. I will try again.

#

At first I tried installing and I got an insecure boot platform error
https://imgur.com/a/nxJzMQ3

Then I tried installing with the GRUB method and got farther but it gets stuck after installation on reboot. At the beginning you can see the screen I get stuck on before trying again.

Can't see shit. Turn around your laptop 😄
I'm not familiar with MacBooks but you might need the nomodeset boot flag. You can add it by pressing e at the boot menu.

mossy magnet Jun 7, 2024, 9:32 PM

#

Sorry about that, I will try your suggestion and give the screen a wipe and a turn for the next set of photos.

mossy magnet Jun 26, 2024, 1:48 AM

#

Hi @idle adder , I tried adding nomodeset, but got the same results. https://imgur.com/a/tE2Kv4U

#

I followed the directions on this page: https://pve.proxmox.com/wiki/Installation#:~:text=Adding the nomodeset Kernel Parameter,-Problems may arise&text=On the Proxmox VE bootloader,e to edit the entry.

#

At this point I wonder if I should abandon ProxMox and try going back to working with HA directly from KVM, or maybe try to start over on a Rasberry Pi or maybe even just a Home Assistant Green?

idle adder Jun 26, 2024, 8:55 AM

#

Or install debian and then install PVE on top.

#

I really don't like SBCs but if I have to use one I'd pick the pi and run HA as do ker container The green is too specialized.

#

You should have replaced quiet with debug btw. We want some information about what is happening.

mossy magnet Jun 26, 2024, 2:41 PM

#

I’ve spent 3 months trying to get a consistent HA setup to run, at this point I will take the simple but specialized option. I just want to get my little blinds project working. The issue I’m having now is that I can’t seem to start back up into my Ubuntu desktop.

Thank you for all of your input @idle adder ! I will close this thread now.
