Can't connect Yeelight to Google Home

I can’t connect my Google Home to the Yeelight app. I’m set on Singapore server. It tries to connect from the GH app, I can enter my Yeelight password (it then shows me logged in), asks me to ‘Give this app permissions’ and says "Linking Your Yeelight Account’ but then returns back to the GH settings.

How can I fix this?
