YouTube login bug locks some users out of the website

Some YouTube users cannot sign in through web browsers even though their Google accounts work in other services and in the YouTube mobile app. Reports span multiple browsers and computers over roughly two weeks, and Google has not publicly confirmed the issue or a fix.

• The bug affects YouTube sign-in only in browsers
• Accounts still work in the YouTube app and on TVs
• Issue persists for about two weeks across browsers
• Google has not confirmed the cause or a fix
