Latest Core Update 2025.6.1 causing issues - SOLVED

I preformed the latest core 2025.6.1 update that popped up today some hours ago, and now Homeassistant OS WebUI has some issues. This install is in a VM on a Proxmox host in my network.

  1. When refreshing/reloading the web page, it takes a long time to fully load the page as the icon/symbol in the browser that represents the page loading doesn’t go away for a number of minutes. What is taking so long to load I’m not sure as nothing appears to be missing from the pages that are accessible. While it appears to be loading, navigating the Homeassistant WebUI appears to work as normal except as noted in the next points.

  2. All integrations fail to load their respective devices page with error “Error while loading page devices.”, though thier respective Entities page loads fine. All the items from the various intergrations appear to be functioning and working fine on the Dashboard.

  3. Trying to access Settings > System also fails to load with a similar error as the integrations error, “Error while loading page system.”

  4. The Settings > About page also fails to load with error “Error while loading page info.”

  5. The Homeassitant app on my Android device however, can access everyhing just fine, so I was able to pull up an error log there. I dont know how I can attach a log here, but one error that is repeated a number of times is:

2025-06-14 01:55:57.155 WARNING (ImportExecutor_0) [py.warnings] /usr/local/lib/python3.13/site-packages/google/protobuf/runtime_version.py:98: UserWarning: Protobuf gencode version 5.28.1 is exactly one major version older than the runtime version 6.31.1 at pyatv/protocols/mrp/protobuf/DeviceInfoMessage.proto. Please update the gencode to avoid compatibility violations in the next runtime release.
warnings.warn(

I dont know if that error is the cause of the issue access the WebUI of HAOS. There are a couple of other errors but they seem related to some intergration and add-on.

Did you try to clear your browser cache ?

I rebooted the HAOS VM in proxmox thinking maybe it didn’t reboot properly after the update, but the same issue persisted.

Never even crossed my mind to try clearing my browser cache since all the time I’ve been running HAOS and doing updates through the WebUI I’ve never experienced this issue. So I did clear the cache and restarted the browser as well and all seems fine now. Thanks.

The update seems to have broken my install. I did the backup but on boot it is sending me to the emergency console stating that the client can’t start. :frowning:

That is good to know, on my VM after update just lost connection

Will rever then to previous version and do a VM backup, my latest backup from Home Assistant is on latest release, and this broken my current ha

Same setup and issue. Proxmox 8.4, 2025.6.1 broke internal communication.

Zigbee2mqtt works, but most integrations are non-responsive. Any calls to download py wheels return that it is not connected to the internet, even though add-ons are communicating fine.

After updating my HA Core version from 2025.5.3 to 2025.6.1 on my Proxmox server 8.4.1 I don’t see any issues at the moment, everything is running and I can communicate with HA web UI from my laptop and mobile device

I realized most, if not all, of the issues I’m experiencing are my HACS-installed custom integrations. Thanks for the data point.
