Fatal error: Uncaught Exception: Failed to connect to database

Hi I migrated a project from 1.4.3 to 1.6.0 but I get the following error docker-compose logs appwrite and the database is shown as disconnected.

TL;DR

Developers migrated project from 1.4.3 to 1.6.0 and are now unable to connect to the database resulting in a fatal error. To fix this error, they should check the database connection settings in the new version of the project and ensure they are correct for the updated version.
