This morning my Chromecast (used for display only on TV) no longer works. An empty rectangle with a missing graphic bug in the upper left corner is displayed for a few seconds, then the Chromecast reverts to the screensaver. This has been operating properly for several months and there have been no network or configuration changes.
I have restarted Roon, the Chromecast, the Win 10 1903 PC running Roon and the problem persists. The Chromecast is connected via 5 Ghz Wi-Fi and the laptop via 1 Gb/s Ethernet. All devices are on the same subnet. Factory resetting and re- adding the Chromecast didn’t help. The Chromecast firmware is version 1.42.172094.
Any insights much appreciated!
