Same here. Outside my house on all browsers HA freeze. Opening in HA companion app no issues are all. Both use same URL to get into HA.
Nothing helping…
On local network everything works perfect.
same here for linux desktop with firefox, the only thing helps refreshing tab.
Perhaps it depends on cards and custom plugins you are running. Any browser console errors/warnings?
Still having this issue. HA version is 2025.10.1. I found some information that this could be some issue with DNS, and this could be the reason, because I use Pi-hole as local DNS server.

I need to test this hypothesis for some time to make a conclusion.
Sounds familiar. I have a dashboard in a browser (LibreWolf/Fedora42) tab and I am working in another tab. Often when I switch to the HA tab, I get an unresponsive view that may take several seconds (sometimes almost a full minute!) to update end become responsive again.
See this video for an example.
I’ve seen similar with Chromium and on Android…
As there is a clock on this dashboard, you can see the clock jumps to the correct time, and then the dashboard freezes until it is reloaded and the clock starts ticking again.
