**Your software**  
My Mautic version is: v2.16.1  
My PHP version is: 7.2.30

**Your problem**  
My problem is: Error with Amazon Aws

These errors are showing in the log:

**It happens that when I refresh the cache it gives me this error in the logs**

[2020-04-26 09:25:37] mautic.CRITICAL: Uncaught PHP Exception Symfony\Component\Debug\Exception\FatalThrowableError: “Type error: Argument 1 passed to Mautic\PluginBundle\Integration\AbstractIntegration::\_\_construct() must be an instance of Mautic\CoreBundle\Factory\MauticFactory or null, instance of Symfony\Component\EventDispatcher\ContainerAwareEventDispatcher given, called in /home/zdgafivm/public\_html/mktg/app/cache/prod/appProdProjectContainer.php on line 12500” at /home/zdgafivm/public\_html/mktg/app/bundles/PluginBundle/Integration/AbstractIntegration.php line 208 {“exception”:"[object] (Symfony\Component\Debug\Exception\FatalThrowableError(code: 0): Type error: Argument 1 passed to Mautic\PluginBundle\Integration\AbstractIntegration::\_\_construct() must be an instance of Mautic\CoreBundle\Factory\MauticFactory or null, instance of Symfony\Component\EventDispatcher\ContainerAwareEventDispatcher given, called in /home/zdgafivm/public\_html/mktg/app/cache/prod/appProdProjectContainer.php on line 12500 at /home/zdgafivm/public\_html/mktg/app/bundles/PluginBundle/Integration/AbstractIntegration.php:208)"}

**And this in configuration for Amazon aws:**

Connection could not be established with host [email-smtp.eu-west-1.amazonaws.com](http://email-smtp.eu-west-1.amazonaws.com) [Connection refused #111] Log data: ++ Starting Mautic\EmailBundle\Swiftmailer\Transport\AmazonTransport !!
