Let me start by saying that I know very little about most of this stuff, but enough to probably be pretty dangerous. So bear that in mind while reading the following.
I have a droplet on DigitalOcean where I set up a Docker with Hassio + Home Assistant. It seems to be all set up correctly, as I can access the Home Assistant interface via my web browser. But when I go to Configuration -> Integrations and attempt to configure Google Cast for my Google Home Mini, I get the “No Google Cast devices found on the network.” error message.
I’m guessing that’s because the Google Home Mini is connected to my home network and in no way connected to my VPS – is that correct? And does anyone have any recommendation of how to get the Google Home Mini to be recognized?
I’m not sure if it would have worked with IPv4 anyway, but port forwarding from my router is limited to IPv6.
Thanks a ton in advance for any insight that anyone can provide.
