Laravel changing /home route after register

I implemented an email activation feature and I have some issues with it. If I open the activation link after I register ,localhost:8000/activate/tokenvariable, it redirects me to the /home url and gives an error. But if I delete cookies and visit it, account is being activated without a problem.

I couldn't understand what the problem is.
