I’m experiencing a recurring issue with my Chromecast integration in Home Assistant using Node-RED.
I have a flow that uses the cast node (from node-red-contrib-cast) to play a mp3 file via a Chromecast device connected via Wi-Fi (with a static ip address). This setup has worked reliably for several years.
However, for the past few days, the Chromecast stops playing audio after some hours. When the flow runs, the cast node throws a generic “client error”. The Chromecast is still online, connected to the network, and responds to voice commands.
If I reboot the Chromecas, the cast node starts working again, but only temporarily.
If I open the cast node and click the magnifying glass to select the device, the Chromecast is missing from the list.
If I then re-deploy the Node-RED flow, the Chromecast reappears in the node and casting works again for a while.
I didn’t change anything in my network/hassio setup… so, whats going on? How can I fix the issue?
