I was using my chromecast earlier through the "cast my screen" option in the google home app. It worked perfectly. Suddenly when I press cast my screen, the TV screen turns black, it says "casting has ended" a few seconds later, and then it says chromecast can't connect to wifi, or something to that effect. I did a factory reset, unplugged and plugged chromecast back in, uninstalled and reinstalled the home app, and restarted my phone. Nothing worked. Please help!
