Laravel 5.7 login redirects to 404 page

I'm having an issue now after installing laravel-math-captcha though it was working fine for 2 days with Laravel 5.7 when I login with correct credentials I get redirected to a 404 page. I debug the login process

die($this->sendLoginResponse($request));

and I get

HTTP/1.0 302 Found Cache-Control: no-cache, private Date: Wed, 10 Oct 2018 13:01:35 GMT Location: http://127.0.0.1:9500/404 Redirecting to http://127.0.0.1:9500/404. 

Any idea how to solve this issue and why did it appear?
