Hi and thank you for reporting this. The behaviour is actually expected, the "Maintenance" banner is shown if the page cannot connect to our authentication backend - this could be for various reasons, including the browser being completely offline. It is out of scope for us to dig into the deeper causes from the browser side when a connection error occurs. That said, I agree that the wording could be better to not confuse users. We will discuss this. Thanks again for taking the time!
