Cant play a game

Iam using chrome browser

Today when i want to play a game then this appears on a new page

{"ok":true,"hook":{"id":"59pwRb84"}}

@thibault

I started getting
{"ok":true,"hook":{"id":"uUmWxUrP"}}
How can I get out of this error condition?
(I've tried clearing the browser cache and logging out, but this persists).

I get similar messages, e. g.:
{"ok":true,"hook":{"id":"UOpfuRGY"}}

same here

{"ok":true,"hook":{"id":"xlR0MO6r"}}

at me its working again!
