I want to install mautic on my ubuntu server with nginx. I used the latest package ([https://www.mautic.org/download/latest](https://www.mautic.org/download/latest)) When I first load the page and the installer should start I get the following error message: " Uh oh! I think I broke it. If I do it again, please report me to the system administrator! 500 Internal Server Error" And the server log: ```auto mautic.CRITICAL: Uncaught PHP Exception Doctrine\DBAL\Exception\ConnectionException: "An exception occured in driver: SQLSTATE[HY000] [1045] Access denied for user ''@'localhost' (using password: NO)" at /usr/share/nginx/html/mautic/vendor/doctrine/dbal/lib/Doctrine/DBAL/Driver/AbstractMySQLDriver.php line 103 {"exception":"[object] (Doctrine\\DBAL\\Exception\\ConnectionException(code: 0): An exception occured in driver: SQLSTATE[HY000] [1045] Access denied for user ''@'localhost' (using password: NO) at /usr/share/nginx/html/mautic/vendor/doctrine/dbal/lib/Doctrine/DBAL/Driver/AbstractMySQLDriver.php:103, Doctrine\\DBAL\\Driver\\PDOException(code: 1045): SQLSTATE[HY000] [1045] Access denied for user ''@'localhost' (using password: NO) at /usr/share/nginx/html/mautic/vendor/doctrine/dbal/lib/Doctrine/DBAL/Driver/PDOConnection.php:47, PDOException(code: 1045): SQLSTATE[HY000] [1045] Access denied for user ''@'localhost' (using password: NO) at /usr/share/nginx/html/mautic/vendor/doctrine/dbal/lib/Doctrine/DBAL/Driver/PDOConnection.php:43)"} [] ``` I also deleted the cache, but nothing changed. Why there is a Access denied for user ‘’? This information should be set during the installation i guess. Any idea what’s going wrong here? ---
