Illuminate\Database\QueryException : SQLSTATE[HY000] [2002] Connection refused (SQL: select * from information_schema.tables where table_schema = LaravelBlog; and table_name = migrations and table_type = 'BASE TABLE')

I get still this kind of error after typing: "php artisan migrate" in sudo mode.

Here is mine first lines of .env file: APP_NAME=Laravel APP_ENV=local APP_KEY=base64:XJz8GyJdyJc4KIG/Pdi9uhbzT+uP/BdLd7ftv+VgoDk= APP_DEBUG=true APP_URL=http://localhost

LOG_CHANNEL=stack

DB_CONNECTION=mysql DB_HOST=127.0.0.1 DB_PORT=3306 DB_DATABASE=LaravelBlog; DB_USERNAME=root DB_PASSWORD= UNIX_SOCKET=/Applications/MAMP/tmp/mysql/mysql.sock

Tried to change DB_PORT number(into 33060),DB_HOST from 127.0.0.1 to localhost, put in UNIX_SOCKET(dont know if it works with or without it) As a programming starter(after basic Java course) i feel that mine possibilitties are at the end of road. Can i get help from anyone to overcome those issues?

I can give any additional information to post If this can be a hint im using VirtualBox Ubuntu 18

Thanks
