Why is the migration knocking on an unnecessary host?

Question

symfony

Help me please. i have two virtual machines ds-dwh-dev-pgdb (where mariadb and postgres databases are installed) and ds-dwh-dev-php (nginx, php-fpm + php-7.2.29, rabbitMq, git.) where i and should do the migration.
When I make a migration, I get an error
when migrating posgtres

An exception occurred in driver: SQLSTATE[08006] [7] FATAL: no pg_hba.conf entry for host "10.253.7.51", user "DCredit", database "postgres-slave", SSL off

on mariadb migration

An exception occurred in driver: SQLSTATE[HY000] [1045] Access denied for user 'root'@'10.253.7.51' (using password: YES)

Everywhere he knocks on the host where the project is, but I need where the database is. db host is specified in the settings.
