Symfony 4.2 doesnt connect to Microsoft SQL Server - php

Question

I'm setting up a new project on Symfony 4.2, and I'm trying to connect to Microsoft SQL Server as database, so I have the following files:
/config/packages/doctrine.yaml:
parameters:
# Adds a fallback DATABASE_URL if the env var is not set.
# This allows you to run cache:warmup even if your
# environment variables are not available yet.
# You should not need to change this value.
env(DATABASE_URL): ''
doctrine:
dbal:
# configure these for your database server
driver: 'pdo_sqlsrv'
#server_version: '5.7'
default_table_options:
charset: utf8mb4
collate: utf8mb4_unicode_ci
url: '%env(resolve:DATABASE_URL)%'
orm:
auto_generate_proxy_classes: true
naming_strategy: doctrine.orm.naming_strategy.underscore
auto_mapping: true
mappings:
App:
is_bundle: false
type: annotation
dir: '%kernel.project_dir%/src/Entity'
prefix: 'App\Entity'
alias: App
/.env part:
###> doctrine/doctrine-bundle ###
# Format described at http://docs.doctrine-project.org/projects/doctrine-dbal/en/latest/reference/configuration.html#connecting-using-a-url
# For an SQLite database, use: "sqlite:///%kernel.project_dir%/var/data.db"
# Configure your db driver and server_version in config/packages/doctrine.yaml
DATABASE_URL=mssql://sa:root#DESKTOP-A9GIM4A\ISTANZA:1433/linkontro
###< doctrine/doctrine-bundle ###
MSSQL Service is running correctly, but when I try to run on CLI:
php bin/console doctrine:schema:validate
it returns this error:
Mapping

[OK] The mapping files are correct.

In PDOConnection.php line 31:

Any clue of what's going on?
I tried to write a simple PHP script to check the connection, and it worked.
So credentials are correct, MSSQL Service is on, but the only one who can't connect is Symfony.

Answer 1

From the error description: the php-initiated connection is refused by the MS SQL server. This could mean:
there is no server listening on the address/port you are trying to connect to. Maybe DATABASE_URL is not set correctly and doctrine is trying to connect to the driver's default (i.e. localhost:1433)
the server you are connecting to (or some firewall in between you and the server) is refusing connections - but this is less likely.
Try to add a -v or -vv to the command for more verbosity.

Because of the \ and some unknown reasons,
I find it easear to have it to work using the yaml configuration like following.
doctrine:
dbal:
#url: '%env(resolve:DATABASE_URL)%'
#driver_class: Realestate\MssqlBundle\Driver\PDODblib\Driver
driver: 'pdo_sqlsrv'
host: DESKTOP-A9GIM4A\ISTANZA
dbname: linkontro
user: sa
password: root
