Google Home stopped recognizing Chromecast

So I used to be able control my Chromecast using my Google Home, but a few weeks ago it stopped recognizing it and when I give it a command, it responds “it looks your video devices are offline, you might want to check if they are on and connected to the internet”. Of course, my Chromecast is online. As I type this I’m casting a YouTube video from my phone. I know Chromecast sees my WiFi since the WiFi name is on the screen in the top right under the name of my device. When I go into the Google Home app, I see my Chromecast, so it’s a bit confusing. Anyone have an idea how to fix this? It’s not the most important thing in the world, but it is quite nice to control video by barking commands at my Google Home. Thanks.
