[Bug] Configuração mysql - wordpress

Ao realizar o passo de alteração do arquivo /srv/www/wordpress/wp-config.php e ao executar o playbook o erro ' Error establishing a database connection' fiz a pesquisa do erro relacionado, a pesquisa apontou alguma divergencia no arquivo de configuração nos campos alterados, porem ainda não consegui indentificar o erro caso tenha algum. Segue meu playbook criado para essa atividade:
