The way I solved this was by setting up a hotspot on my phone with the same SSID as my home network. The Chromecast doesn’t know the difference.

I just tried registering as well, same issue. It looks like a problem with their registration process, I tried resetting my password and it was unable to find my email.

Real reason? Because product managers are idiots.

I’m somewhere between step 7 and 8.

Don’t you dare even look at the Øresund, we still have our sticks.
