Sorry, noob here.
My Chromecast integration was working fine but has stopped. I recently upgraded my network hardware but I can't remember if it stopped working before that or not.
I'm using a Ubiquiti USG, switch and WiFi access points. My Hubitat is connected to the switch and I have 5 Google Home Assistant devices connected via WiFi. They are all discovered and appear in the device list.
Sometimes one of them will randomly start working but most of the time they don't and I get error messages in the logs like this:
Can anyone tell me what's going wrong?
