CSRF _token mismatch with 419 error

I would like to connect to my Nova dashbord but when I enter my username I receive a 200 but without page redirection.

On the second click, I receive this error.

	 "message": "CSRF token mismatch.",
		"exception": "Symfony\Component\HttpKernel\Exception\HttpException",
		"file": ".../vendor/laravel/framework/src/Illuminate/Foundation/Exceptions/Handler.php",
		"line": 226,
