I have magento 2 running with this vagrant setup https://github.com/rgranadino/mage2_vagrant and Im receiving this error when trying 

php bin/magento indexer:reindex

If I change the db host in app/etc/env.php to localhost instead of 127.0.0.1 I get

STUCK!!

If you are connecting to DB over SSL connection try disabling that in the env.php and at your DB server level and try again.

'driver_options' => [
1014 => true,
1009 => '/etc/ssl/MySQL-Cert/XYZcrt.pem'
]
