Can't login through cloud web app

Tested on several devices, different browsers, all have unexpected behavior.

Opening web.airmessage.org on Mac Safari (Same MacBook the Airmessage server is running) gives a blank page.
Opening on Brave browser on iOS presents the page but after successfully signing in through Google, the page does not change. Tapping it again dos nothing.
Opening on Safar on iOS has the same effect as above.
