Home Assistant isn't responding

Mobile Apps Home Assistant Companion for Android
1

Hello friends,

I am facing a serious problem since I updated my dashboards three days ago.

When I launch the companion app for Android, most of the time it behaves as follows:

  • It shows me the HA logo on a black background and a loading indicator on top of it (not below) for the fraction of a second. Sometimes the loading indicator does not appear.
  • It shows a completely white screen for several seconds. In rare cases the screen is not white but black with only the HA logo in the center.
  • I get the message that “Home Assistant isn’t responding”. I have the options to wait (which does not help) or “OK” to close the app.

Sometimes the app launches normally showing the screen with the HA logo, the loading indicator below it and the Open Home Foundation logo at the bottom of the screen and then loading into the dasboard within a second.

I just don’t know how to figure out, why and when this happens.
Sometimes the issue occursif I am on my local network and if I turn wifi off and connect via mobile network it works. But sometimes the issue occurs when I am not at home and try to connect from the outside. So it cannot really be an issue of the proxy configuration since it all seems to work sometimes.

But the really strange part is that I can always access HA from anywhere on any network in a browser. Any browser including the kiosk browser tablet and all services (hass.agent etc.) work without any issues. Even the companion app on my wife’s phone does not show any problems. It is only the companion app on my phone which has this issue.

Of course I have already deleted the app’s cache and data, uninstalled and reinstalled it etc. Nothing helped.

Is there anything else I can do?

I do always access the HA instance over a top level domain hostname. It leads to my local static IP via a A record and is always available. The requests are forwarded by nginx running on a seperate machine and local requasts are redirected to nginx using dns rewrites by adguard. This worked flawlessly for over a year now.

App version: 2025.8.7-full

Home Assistant OS:
Core 2025.8.3
Supervisor 2025.08.3

Can you confirm you mean AAAA record which will resolve to an IPv6 address as opposed to an A record which will map to an IPv4 address?

Is your router set-up to allow trafffic into your proxy for IPv6 and is the proxy configured to handle IPv6?

If you are not using IPv6 then remove the AAAA record and just use the A record.

Oh, no. It’s just an A record.
Sorry for the confusion. I updated the original post.

Might be the same issue as this. Check the linked Github issue - there should be a companion app update being released once Google approves it.

Yeah, look much like my issue.
So I will wait for the update and report back.

Hi everyone,
I have the same/a similar problem. When I start the App, it taks about 10 sec, befor I can see the screen.
Yesterday I figured out what the problem is (at least for me).
I have multiple servers set up in my companion app. I always use the first server at home. The other server is at my dad’s home, and I only access it via VPN. So I can only use either my server or my dad’s, since they are not in the same network.
Apparently, HA tries to connect to both servers when I launch the app or at least test the connection.
After deleting my dad’s server from the app, the app starts immediately as before.
This solution isn’t optimal, though, because I have to connect to the second server at least once a day to check if everything is working properly.

That’s another issue and not related to my problem.

Initially it looked like this had fixed the problem for me also, but it hasn’t.
A couple of restarts later, and the white screen is back.

I have to say, I switched to a new phone in the meantime. This one does not have the issue, so I cannot say anything about it any more.

So, the problem version on my phone was 2025.8.7-full

I noticed here:-

That v2025.9.2 had been released, but on my phone, that was not showing as an available update via the playstore.

So I downloaded the apk from the page above and installed it, and it appears to have resolved my issue.

Hi @HARookie , i have exactly the same.

Did you maybe found a fix already?

Hi,

I’m very sorry, I missed that message.

You can find everything regading that topic on GitHup:

I tested the app and dropped the second server and added it again and I tested that with different versions of the app.
And a developer directly fixed it.
The result of all fixes and tests was that everything works fine again starting with version 2025.9.1 (as before 2025.8).
I wrote a message on GitHub a Sept 1.
I don’t know if a version 2025.9.x is available now in google playstore. I downloaded the version directly from GitHub as even at end of Sept. there was 2025.8 versions only.
