Laravel: SQLSTATE[HY000] [2002] Connection refused

Question

I am using Vagrant with fresh laravel 5.4 installed. After I run auth I have ran the migrate to migrate the MySQL tables. All of these process successful but when I try to login or register to test the system I am getting error:

SQLSTATE[HY000] [2002] Connection refused.

But my database working perfect since I already able to migrate the tables. Whats possible solution could be? check attached image (I'm using Ubuntu 16.04)

Solution

Try changing your DB_HOST from 127.0.0.1 to localhost. and if still not working try using the default mysql port to 3306
