Chromecast Receiver App Error: The WebSocket disconnected unexpectedly: undefined
问题 I'm trying to get a basic chromecast app setup where I can send a simple custom message from Desktop Chrome to the Chromecast receiver. The devices is whitelisted, and the app sources are sitting at the url specified during the whitelisting process. Additionally the correct API_ID is being used and the NAMESPACE is the same for the receiver and sender apps. The receiver app loads, but just after that I get: [ 0.230s] [goog.net.WebSocket] The WebSocket disconnected unexpectedly: undefined This
