Connect to Mongo Atlas timeout happened sometimes with PHP library

Description

Hello pro,

Im using PHP library and PHP 7.0.30, Mongo Atlas Free Tie and tried to connect, It's successful but looks too slow. I also connected via command line and it's worked as well. When using PHP, 10 times connection got 8 timeout, other times connected, get, insert, update data as normally.

This is my connection code:

$client = new \MongoDB\Client("mongodb://<USERNAME>:<PASSWORD>@mycluster0-shard-00-00-bez3z.gcp.mongodb.net:27017,mycluster0-shard-00-01-bez3z.gcp.mongodb.net:27017,mycluster0-shard-00-02-bez3z.gcp.mongodb.net:27017/test?ssl=true&replicaSet=MyCluster0-shard-0&authSource=admin&serverSelectionTryOnce=false&serverSelectionTimeoutMS=15000");

This is my timeout info:

MongoDB\Driver\Exception\ConnectionTimeoutException: No suitable servers found: `serverSelectionTimeoutMS` expired: [connection timeout calling ismaster on 'mycluster0-shard-00-00-bez3z.gcp.mongodb.net:27017'] [connection timeout calling ismaster on 'mycluster0-shard-00-01-bez3z.gcp.mongodb.net:27017'] [TLS handshake failed: -9806 calling ismaster on 'mycluster0-shard-00-02-bez3z.gcp.mongodb.net:27017'] in src/addons/HbinAws/vendor/mongodb/mongodb/src/Collection.php at line 262

Please help !

Assuming you're using macOS (per #853), I believe you may be hitting PHPC-1169. The actual bug is CDRIVER-2624 (since fixed upstream) and will be available in PHP driver 1.5.0 (due to be released within the next two weeks). If you require an immediate solution for your development environment, you can manually compile the driver from the master branch of this repository (effectively 1.5.0-dev).

Please read my replies in #791 (comment) and #791 (comment). Additionally, you can run the CLI script in my second reply to confirm that you are hitting the same issue.

@jmikola Thanks you ! Command line is works well.

I'll close this. Please follow #791 for updates, as I'll make a note there when 1.5.0 is released on PECL.

1.5.0 is now available on PECL. We'll have a formal release announcement tomorrow.
