I have a Unifi network, a Google Nest hub and https://cast.home-assistant.io/ on the google Nest device.
Since 2 days I have the strange issue that the Google Nest hub after 10 minutes the connection drops on the screen and the https://cast.home-assistant.io/ still thinks, tells me that it is casting.
I checked the log on the Unifi Controller for the hub, no package lost, the connection stays good.
Rebooted home assistant, Google Nest hub and reconnected several times cast home assistant, but every time after 10 minutes the screen casted is dropped.
Hope to hear from someone.
