smtp - Symfony 5 Mailer

Question

I am unable to make Symfony Mailer work on my hosting with Let's Encrypt SSL certificate installed:

My .env configuration:

MAILER_DSN=smtp://contact@[DOMAIN].com:[PASSWORD]@mail.[DOMAIN].com:465

Error:

request.CRITICAL: Uncaught PHP Exception SymfonyComponentMailerExceptionTransportException: "Connection could not be established with host "ssl://mail.[DOMAIN].com:465": stream_socket_client(): SSL operation failed with code 1. OpenSSL Error messages: error:14090086:SSL routines:ssl3_get_server_certificate:certificate verify failed" at [SERVER ROOT].com/vendor/symfony/mailer/Transport/Smtp/Stream/SocketStream.php line 138 {"exception":"[object] (SymfonyComponentMailerExceptionTransportException(code: 0): Connection could not be established with host "ssl://mail.[DOMAIN].com:465": stream_socket_client(): SSL operation failed with code 1.
