Describe the issue

Ever since I updated to Roon Version 2.54 a week ago, any Chromecast streaming devices vanish from the list of Audio devices after a couple of hours.
I have an Android TV which I don't use for Roon, and a Nest Audio that I use for Roon.
After restarting roonserver, the devices are back, but always vanish some time later.

My Roonserver runs on Ubuntu 24.04.3 LTS, and the device is a Google Nest Audio speaker.

Describe your network setup

roon server is on wired network, which is bridged with the Wifi network of the Nest Audio (same subnet). There is a hifiberry on the same subnet, which never causes any trouble.
