Suddenly stopped connecting to the database?

Question

MySQL

yesterday I created another machine for VirtualBox next to the homestead one - the homestead did not touch. Today vagrant began to give an error when entering the local site

SQLSTATE[HY000] [2002] Connection refused (SQL: select * from `tasks` order by `created_at` desc limit 3)

Although it was still working before it was created. and now I can not connect via DataGrip to the database
