No longer can access HA on Pi 3

Installation Home Assistant OS
1

I can no longer access HA on my Pi 3. All of my room sensor boards are no longer connected via. MQTT as well.
I have tried re-imaging a brand new micro SD card with all three images with the same result.
After using Etcher re-imaging a new micro SD all goes well. I get the standard splash window that it might take HA up to 20 minutes to update. Eventually, I get the login screen. I’ve tried both my existing login and new login’s with the same result. All I get is the spinning HA logo with connecting. I’ve let it run all night, no difference.
I have three ports forwarded on my router 3218, 1883 and 8123 both port range and local.

Have you tried a different browser or private mode in your current browser?

Hi, Yes… Same result.

Which SD card image are you using?

How are you connecting the pi to tthe network?

If using HassOS and connecting via wireless, make sure you follow step 3:

Also make sure you have the correct image file for your hardware.

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

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…

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

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