Can't login to cloud.dgraph.io

When I try to login to cloud.dgraph.io using GitHub, I just see a blank website with a spinning wheel. When I look at the console I see two unauthorized requests (status code 401) to https://cerebro.cloud.dgraph.io/graphql. It used to work a couple of days ago, but I don’t understand why it has stopped now. After removing every cookie, I don’t get any error but still cannot go past the blank loading page.
