Can't access HA via IP after install

I successfully installed HA 12.4 on a Thin Client and I got the IP address page and everything.

When trying to access the IP address + “:8123” on my desktop, it gives me a “site cannot be reached” page. Same when I try “homeassistant.local:8123”.

I pinged the IP and I’m getting a response. Both the desktop and Thin Client are plugged in via ethernet to a switch.

Any suggestions on what needs to be fixed?

For what its worth (if relevant), I installed HA via a VM on this desktop when first diving into HA. Not sure if that affects anything. I uninstalled everything before setting up the Thin Client.

Please help!! Lol

HA 12.4? Current version is 2024.8.2.
Just to make sure: You used http://? https:// won’t work.

Can you attach a monitor and keyboard to the pc?

Just chiming in in case it can help.

I guess you are trying with “http://ip:8123

  • are you sure the IP is correct
  • can you ping that address and get a reply
    Make sure you know the current IP address from your HA and preferably make it a fixed one instead of distributed by DHCP.

I wonder if http://homeassistant.local:8123 is not referring to the old install, don’t know how mDNS works.
If you don’t add the protocol in front of an address, your browser might default to httpS

As @francisp says: connect at least a monitor to the thin client, so you can see what is going on and what the current IP is if you have no other ways to find out

The thin client boots no problem. Observer works too. See below.

I’m completely lost on what is wrong. Doing both “192.168.1.59:8123” and “homeasssitant.local:8123” on my desktop doesn’t work. Shows me a “Cannot reach” page



Ping

I think he is referring to HAOS version

OP- What version of Core are you running?

This is a confusing statement. *** HOW *** did you install Home Assistant? And, on what host?

Yes apologies. I’m running 12.4 OS version.

2024.8.2 core

Sorry if confusing.

When waiting for my thin client to be shipped, I set up HA on my desktop by using virtual box to just get familiar with dashboards, etc.

I only mentioned that because I wasn’t sure if doing that is now somehow screwing up my ability to access HA now on the same desktop after I set up the thin client

You still haven’t said HOW you installed Home Assistant.
How: HAOS, Core, Supervised?
Host: Bare Metal, Container, Virtual OS?

If you want to save any automations or installed integrations from the test installation, just do a full backup- save the .tar file to a thumbdrive. Turn off the test system because they can’t both be at homeassistant.local (this will confuse MDNS). Turn on the new installation and do a restore.

I don’t want to do any of that. I want to start fresh with the thin client. I simply mentioned the virtual box as background in case it was what was causing me being unable to connect to the IP.

Please see my prior comments. I cannot connect to the IP address whatsoever

Can you try to connect from another client/browser?

I tried my laptop and plugged it directly into router. Same issue. Can’t connect

What about that?

Idk what any of that means. I’m brand new to this. I followed this basic guide to get HA on my desktop via virtual box.

I completely uninstalled virtual box before installing everything on my Thin Client.

Ok, but what/how did you install your thin client?
It’s not easy to help you if we don’t know.

I ran Ubuntu off a USB. It all installed successfully. See my above screenshots.

It lists an IP, no errors when starting it up.

On that screen (from the screenshot), enter

login
docker ps

what do you get ?

See below (sorry, a bit tough to see). Thoughts?

Seems the homeassistant container is not running.

Try the following
first

exit

to leave the shell, then

ha core start
