Ambient Weather Initial Setup "Unknown Error"


I’m working to get the Ambient Weather integration set up to allow HA to pull data from my Ambient Weather weather station. I have the API Key and Application Key from my account, but when I go to set it up, it waits for about 60 seconds and then just returns an “Unknown Error”. This happens regardless of what API and Application key I enter.

The HA instance is a brand new one that I created in VirtualBox from the latest image available from the Home Assistant website.

The only relevant log entry I can find is below. Any suggestions as to what I can do here?
