Unfortunately, suddenly starting from today, I experience the same.
I can’t start the HA anymore, it hangs on Connection Lost. Reconnecting…
I can’t get in the system anymore, dashboards are not loaded, I can’t do a safe restart, it simply got stuck, and remains stuck, also after switching off the power of the computer (HA Green)
Anybody a suggestion on how to get in the system again?
same here, happens every ~15 minutes when not using the app. i get the same message in webapp on my pc, android app and assist widget hangs as well. they all get back to work after a while, but it’s simply annoying
Your router is one single point of failure. Try streaming a video on a laptop while you are looking at the dashboard. If you see the video buffering at the same time as your dashboard goes unresponsive, then my bet is on the router.
Same problem here. It’s been doing it in the MacOS app for some time now. When I upgrade to 2026.1 it started happening in the Safari browser. It does when viewing settings pages. My computer is connected via an Ethernet cable as is the Home Assistant VM.
+1 I have been dealing with it for a few weeks (that I noticed). It started on web browser as moderate annoyance to full fledged automations quit running and I cant get but occasional screens loading. Companion app is no go. I moved it to a reserved IP range and it is worse now on my ASUS rtr- since a while back I had an issue with a Synology until I moved it to new static IP outside DHCP. I had disabled a few integrations, but cant get in to do more right now. I may have to go hard reboot computer since virtual boots never cleared much and the logs didn’t look to noisy when I had a chance to look.
update… While the restart from HA settings/system didnt work, and got so bad page wouldn’t finish loading to restart from app. So, I went and hard reset the computer and it seems to be operating fine now (using a cheaper amazon mini-computer loaded with HA OS). I will monitor it as I am not sure what was wrong in my case.
You can request a fix here…
I’m happy I’m not the only one with this issue. I’m extremely annoyed by this and sad it’s not fixed for such a long time.
If not yet stated: it happens regardless connection. In local network as well as via LTE/Nabucasa.
It’s even more annoying that it cannot recover on its own (I waited for 5+ minutes).
Have you checked your router system log?
Hi everyone,
I think I've been having the same issues for a few days or weeks now. My Nabu Casa connection drops every few minutes, and then my entire connection (internal/external) freezes.
I’ve read that this might have something to do with the DNS. I use AD Guard Home and have configured a few fallback DNS servers (Quad9, Google). I’m not sure if that’s the problem, and I don’t know where to look to find out.
I have a complete Unifi setup with a UDM, but I haven’t changed anything there.
Everything has always worked in the past, and it’s not as if the connection doesn’t work at all.
On the NabuCasa homepage, I see “connected,” but a few minutes later it’s back to “offline.” This doesn’t happen at regular intervals either.
Does anyone have any idea what’s causing this? I can’t even access my Home Assistant properly locally when the connection to NabuCasa isn’t working. The only thing that works is to disable it completely.
Looks like the token was corrupt. After logout and login problem seems to be solved
