After updating the mautic to latest 4 i cant login

When I open the browser url it redirectls me here

Why it tries to redirect me to /mautic…there is no folder there I get this error

I'm sorry! I couldn't find the page you were looking for.

#### **404** Not Found

If I change url to I can see login window but after submitting the login it takes me back to and 404 page

ok fixed this by changing site_name in the local.php
