AlterBrains

If using Joomla in a DDEV environment, you cannot connect Alter Reports to a MySQL/MariaDB database by using "localhost" or "127.0.0.1" as the host. That address is valid only from your host machine, not from within the Docker container where Joomla runs. The host must be "db" and the port must be set to "3306". I thank Claude for discovering the cause of my initial frustrations with Alter Reports

It's not a problem with Alter Reports, it's the standard container name resolution in Docker.

I don't see any issues here.
