I can't login to chat.meta.stackexchange.com. When I click the login link from inside a chatroom, the page reloads and I seem to be redirected right back to the room, without being logged in. Same when I click the login link from the topbar.
I've tried clearing all my cookies matching
stack. This quite effectively logged me out of everything else, but it didn't help my situation on chat.mse. I also tried a global logout, to no effect. I can log in successfully from an incognito window.
