I have the Google Calendar node configured in the Node Red add-on to hass.io. I did this ages ago, so I'm not sure if I had much trouble.
Now I want to use the same node in another Node Red Docker install on another machine. I've create a new client & secret, and updated my laptop's hosts file to redirect
192.168.0.18 but when I click on "Authenticate with Google" I'm getting "redirect_uri_mismatch". If I browse to
http://node-red.example.com:1888 it opens Node Red, so the hosts file update looks correct (that container maps 1888 to 1880).
Any ideas on what I'm doing wrong?
