No longer can access HA on Pi 3

Installation Home Assistant OS
5

Thanks for your reply… I got it working by using a new (never used) user name and password but are still not able to get Duck DNS working.

I am having the same issue… Basically a stock installation of Hassio that I’m trying to configure. Here is what I noticed::

Yesterday, I couldn’t access via Firefox browser. Not sure why but Chrome works. Didn’t worry too much about it thinking that it was a fluke.

Tonight, I connected to http://hassio.local:8123 using Chrome, rebooted Hassio from the UI and now:
“This site can’t be reached
hassio.local refused to connect.”

I’ve tried 4 different browsers and multiple machines. I can ping the Pi’s IP with success AND I can see the SAMBA on my network.

The only thing I’m playing with in the config is setting up MQTT- and that is basic from the Hassio store.

any help is greatly appreciated. Spending too many hours on trying to get the configuration working.

Should also mention that I’ve tried a 2nd RPI 3B+ with same results.

Did you try connecting to http://[pi’s ip address]:8123

Did you install duckdns? If so you will need to navigate to https://…

Yes I tried to log in with the PI’s IP address as you suggest. I have not enabled DuckDns yet until I get the system up and working.

I should note, I can also ping the IP of the PI with success on my network…

Am I unique here? I always keep my computer up to date- and yesterday, I did a Java update for the VPN software I use for work…

I don’t think that would have an effect if you are only connecting locally.
Being able to ping the pi is a good sign.
Can you connect from another PC/tablet on the network? That would prove or disprove your theory.

11

Tried a different PC without success… I have NO idea what caused this.

Through Samba, I commented out the simple change I made to configuration.yaml. I was hoping that I’m not the only person experiencing this.

Hi,

Have you tried re-booting your router?
Are you hardwired or using WiFi?

Keith

13

Yes- I rebooted the router. I am using a hardwired connection.

The physical port on the router works- I validated that as well as the cable. Also tried swapping out the Pi…

Hi Pete,

I use Chrome exclusively with no issues.

I’m sure it’s not hardware. So you intermittently connect within your firewall?

Keith

15

Keith-
I’d say its a no connect to the UI at this point and yes this is within my firewall.

I can still reach the PI as I mentioned earlier- I copied the config.yaml out for b/u purposes for example.

Any help is greatly appreciated! I’d hate to start-over out of default… though my learning curve is much less at this point

Thanks,
Pete

If you can get your yaml file you wont have to start from scratch. Can you get the config/home-assistant.log file? Does that shed any light on what is happening?

17

I was unaware of the log file quite honestly. After investigating the log, it pointed me to an error in config.yaml

I honestly had an extra space in configuration.yaml that caused this.

Thank you all for your help! I’m getting close… and dangerous!

I have the same problem. I set up duck dns as well. everything was working fine and all of a sudden it stopped. (without me making any changes to the files…
How can I get into the config file? any idea please help…

19

Is SSH or SAMBA still working?

If not you can remove the SD card and read it on a PC. Config file on SD card

20

Would you post your configuration file so I can take a look.

21

Thanks for replying so quickly. You guys are great.
The device does show on my mac in the network section but unable to connect.
I set it up and had it running for hardly a week, and it stopped working without me changing a thing.
The trouble shooting I did was.

  1. Restart Pi3 multiple times
  2. Disconnect and connected back the LAN cable multiple times
  3. Checked if the IP of the Pi3 is same as what is assigned in the port forwarding and in DuckDNS. (I didnt change anything in the first place to cause the problem)

I did plugin the SD card into my Mac but was not able to read anything on the SD card so I left it. Looks like tom_I has suggested a way to do that. I will try it and let you guys know the content of the configuration file. If Hass IO is that unstable then I dont think its made for me :frowning:

22

That software was for a windows PC not a Mac. I think you should be able to read it without the software if you are using a Mac.
Grab your config/home-assistant.log file as well.

Two other things that are important for stability:

  1. a 5V power supply capable of supplying 2.5A. A phone charger will probably not do.
  2. a good quality SD card.

You need to format your pasted code as per the blue banner at the top of the page.

Which line is line 88, and what was the error?
