Unable to access lovelace after upgrade to 2021.9.x

I am running HA 2021.8.8 on raspberry Pi4, recently i tried upgrading to 2021.9.0 beta before the official release, after updating I couldn’t access frontend Lovelace at homassitant.local:8123 nor at 192.168.1.200:8123 (ip of homeassistant).
when I checked at homeassistant.local:4357 supervisor was mentioned as connected.
I had to revert back to 2021.8.8 using ssh.
after 2021.9.1 came out i tried again with same result.
skipped 2021.9.2 and 2021.9.3…
so should i upgrade to 2021.9.3?

I seem to have the same issue. After about 30 minutes of running the core container stops. This is since 2021.9.0 and still an issue at 2021.9.3

you are on rpi4 too?

no haos on a VM (esxi)

Same here … tried all versions from 2021.9.0 to 2021.9.4 … all have the same issue that initially all is fine but after 30 minutes there is no connection with home assistant any more … reboot helps for few moments but then again it stops after a while … every time i have to revert back to 2021.8.8 … i am on proxmox and home assistant os …

I’ve also updated from a 2021.8.8 to 2021.9.4 on a rpi4.
I’m not able to connect to the GUI but the rest such as automations are still running.
I’ve also the issue that via cli I wasn’t able to restore a partial update. So now I stuck with 2021.9.4.

To downgrade to the 2021.8.8 the command is

ha core update --version 2021.8.8

I solved this issue by disabling ble_montior integration, updating and again enable ble_montior from GUI. then updating Ble_montior to latest version i.e 5.0.2 from HACS store.

You can access gui by the following command

Ha core restart

Now I am running 2021.9.4 without any issue.

I’ve tried the downgrade of core to 2021.8.8. This did work so far.
I also restarted core as you’ve mentioned but still not access to Lovelace.

NSURLErrorDomain - 1005

meaning you can’t access lovelave even with core downgraded to 2021.8.8?

Exactly!
The screen on my iOS app as well as the web access through any browser doesn’t work anymore.
At the moment I only have access to the cli or ssh login at the rpi itself with an attached display and keyboard.
BTW, I’ve also rebooted the host and checked supervisor connection, but on Port 8123 nothing is coming back.

You’ve mentioned the ble monitor. Do you know how to disable that outside the gui via cli?

check http://homeassistant.local:4357 whether supervisor is running or not?

did so and it said connected.

do you have ble_monitor running?

read this link Common tasks - Operating System - Home Assistant
ad try the following

ha core start

following by refreshing homeassistant url in your broswer

I did restart core followed by by checking the url but without success.

Concerning ble_monitor, I don’t know if it is enabled or not, but I’m also not sure how to check that at the moment.

I will try

ha core start

when I’m back at home and let you know.

In fact I’ve never had an issue after an update, even after updating when I didn’t update for more than 7 months. However now I hope to fix that somehow :sweat_smile:

you don’t have tail scale or zero-tier enabled on your Homeassistant? In fact I am in my office and accessing HA from here over tailscale.

No, at the moment there is not access from outside

I’ve tried to start the core. However I did restart too.
It didn’t change anything. I still can’t access Lovelace GUI.

Update
I found out, that /dev/root has 100% in use. So no disk space left on /dev/root.
All other mounts do have space left, see attached

Can my behavior of lovelace be related to that issue or is that quite normal???

I’ve restored an old backup with an old core (2020.12.2). Now Supervisor is running again and I will try a new update.
Before the problems occured I updated from 2020.12.2 to 2021.8.8 and had no issues.
I forgot to make a full backup on this, when I updatet to 2021.9.4.
