 * Hi there,
 * i got the following error: [https://kb.mailpoet.com/article/200-solving-database-connection-issues](https://kb.mailpoet.com/article/200-solving-database-connection-issues)
 * BUT my database connection consists of an external database server with a custom
   port. Therefore localhost isn’t the problem.
    `DB_HOST = private-asf-db-do-user-
   111111-0.a.db.ondigitalocean.com:25070` (changed real numbers 😉 ) Any ideas 
   how to figure out what happens?
 * `MailPoet Fehler: An exception occurred in driver: SQLSTATE[42S22] [1054] Unknown
   column 'ONLY_FULL_GROUP_BY' in 'field list'`
 * My setup:
 * mailpoet 3.60.6
    WP 5.7 nginx php7.4-fpm mysql 8
