Cannot migrate DB

[donnadonn]

Hello, I have an issue with the "php artisan migrate" command.

• OS: Debian 12 fresh install
• php8.2
• also tested with php8.1, same behaviour

The error is :

   Illuminate\Database\QueryException 

  SQLSTATE[HY000] [2002] Connection refused (Connection: mysql, SQL: select table_name as `name`, (data_length + index_length) as `size`, table_comment as `comment`, engine as `engine`, table_collation as `collation` from information_schema.tables where table_schema = 'laravel' and table_type in ('BASE TABLE', 'SYSTEM VERSIONED') order by table_name)

    833▕     }

I have tried changing the value of DB_HOST from 127.0.0.1 to localhost but then I have another error which is :

   Illuminate\Database\QueryException 

  SQLSTATE[HY000] [2002] No such file or directory (Connection: mysql, SQL: select table_name as `name`, (data_length + index_length) as `size`, table_comment as `comment`, engine as `engine`, table_collation as `collation` from information_schema.tables where table_schema = 'laravel' and table_type in ('BASE TABLE', 'SYSTEM VERSIONED') order by table_name)

Could you enlighten me please ?

By the way, in the .env file, I only changed the DB_PASSWORD value.
