Help for Newby - Cannot Connect to HA

Installation
1

Hi everyone - super newby question here. I’m new to Raspberry and Home Assistant. The Raspberry I purchased and installed HA on for this project is this one:

I can successfully connect to Home Assistant Observer from my MacBook Pro at these addresses:

http://homeassistant.local:4357
http://192.168.1.247:4357

When connecting to either of these addresses, I get to the HA webpage and a message that says:

Home Assistant observer
Supervisor: Connected
Supported: Supported
Healthy: Healthy

That’s the good news. The bad news is I cannot connect to Home Assistant on either of these addresses:

http://homeassistant.local:8123
http://192.168.1.247:8123

Lastly, within my Fios router, when I run a ping test on either 192.168.1.247 or 192.168.1.239, I get the successful message that says, “Test Successful: 4/4 transmitted, 4/4 received, 0% loss”.

What could I be doing wrong? Anyone have any ideas to try? Please treat me like the newby I am. :slight_smile:

Did you try http://homeassistant:8123

Are you able to connect monitor to RasPi and connect from same machine, the RasPi? I think ssh to RasPi and then connect from remote PC will be same affect.

I’m not sure where the second address of 239 came from but if you hook up a monitor to your HA device then you should be able to see the console which will tell you definitively what the IP address is. Is the 192.168.1.x network what the rest of your devices are on?

Just tried http://homeassistant:8123 address from my macbook pro and cannot connect to it. I have a monitor connected by HDMI cable to my RasPi and can see that it is working. I don’t understand your suggestion of “ssh to RasPi and then connect from remote PC will be same affect.” Could you elaborate please?

My monitor connected to my RasPi shows this:

That’s where I got the two ip addresses from. All of my devices are connected on 192.168.1.x.

I also just noticed the message at the top of my monitor (see pic) that says, “Waiting for the Home Assistant CLI to be ready”. Would this have anything to do with my inability to connect?

It might be because you have two connections on the same network, which is not needed. You can try disabling your WiFi from that console to see if it works better:

  • net info (shows your network adapters)
  • net update enp2s1 -e (disabled the network interface name shown in the first command)
  • host restart (reboot)

You can try that to see if having the two interfaces is the issue.

OK. Great. I’ll be back home in a few hours and will try exactly that and report back. Thanks.

Thanks for the net commands. I was able to successfully disable my wif.

However, the problem remains. Here is a picture after my reboot.

I can access http://homeassistant.local:4357 but still cannot access http://homeassistant.local:8123

Any other ideas or thoughts? I’m really at a loss here, especially because this is all pretty new to me.

Here are a few thoughts of things to consider/try…

What browser are you using? try using Chrome and make sure it is not trying trying to sneak in a “https” in your URL instead of “http”.

Try using Incognito mode on Chrome.

Try using a PC/MAC to connect instead of your smart phone/tablet… or vice versa.

Just tried every one of those suggestions. Unfortunately, none worked. On my macbook pro I tried Chrome, (made sure there was no “https”, tried Chrome incognito, tried iphone with Safari, and I don’t have a PC I can use (only a work one). Same results with all. I can access homeassistant.local:4357 but not 8123.

Here is a screenshot of my router:

Probably not the issue, but… Maybe?

I don’t see a default gateway listed in the output you provided…

12

Just looked at my router. It says the IPv4 Default Gateway is 98.118.xxx.x. However, I access my router with 192.168.1.1

That 98.-adress is your WAN adress. There was a similar thread about this, think he solved it by re-installing HA .
