Waha on localhost rather than 0.0.0.0

[DuAell]

From what I understand, waha runs on localhost:3000 and cannot be accessed directly from another container.

The issue happens in Azure Container Apps when a containerized app tries to access the waha container (within the same container app environment)
Changing waha address to 0.0.0.0:3000 should fix it

it opens on both http://0.0.0.0:3000/ and localhost, it doesn't check dns name, but all incoming requests for the port.

Check you network configuration and how your containers are linked
