Since about a month, half of the time I open Chrome from a cold start, the tab that join opens to authorize the device will stay open, going into the console I get an error 404 for the page "join-device.html", below you can see the error. It is not DNS issues otherwise the authorize page itself will not load.
The strange thing is that sometimes it works, others no.
(There is also a google warning about the deprecation of a Google authentication library.)
