Please do not open 2 Topics for the same Issue, this will not help you. Specify the Problem please! You have BasicAuth enabled. The First "Login Screen" will always be without Googles 2FA when BA is on. If you do not get 2FA in the Main Login Screen after the BA Screen try to disable and enable it again. You can try to verify all Modules by hitting the "Fix Panel" Button. If this all does not work you can answer here again.
