I get this error No suitable servers found (serverSelectionTryOnce set): [connection refused calling ismaster on 'localhost:27017']
I am using laravel 7
and this is config / database.php
'mongodb' => [
'driver' => 'mongodb',
'host' => env('MONGO_DB_HOST', 'localhost'),
'port' => 27017,
'database' => env('MONGO_DB_DATABASE'),
'username' => env('MONGO_DB_USERNAME'),
'password' => env('MONGO_DB_PASSWORD'),
'options' => [
'database' => env('MONGO_DB_DATABASE') // sets the authentication database required by mongo 3
]
],
and this is .env
DB_CONNECTION=mongodb
MONGO_DB_HOST=localhost
MONGO_DB_PORT=27017
MONGO_DB_DATABASE=halosis
MONGO_DB_USERNAME=
MONGO_DB_PASSWORD=

What should i do for resolve that problem.
Thanks in advice:)

This has nothing to do with this library. You've error that connection is refused.

Double-check that your MongoDB is accessible at that address.

Thanks!

    Enable MongoDB's free cloud-based monitoring service, which will then receive and display
    metrics about your deployment (disk utilization, CPU, operation statistics, etc).

    The monitoring data will be available on a MongoDB website with a unique URL accessible to you
    and anyone you share the URL with. MongoDB may use this information to make product
    improvements and to suggest MongoDB products and deployment options to you.

    To enable free monitoring, run the following command: db.enableFreeMonitoring()
    To permanently disable this reminder, run the following command: db.disableFreeMonitoring()
