recently, I created an app using the Edge Siemens ecosystem's App Publish tool, where the Docker Compose file includes several associated services. However, after deploying it on the Industrial Edge Device (IED), the service name connections don't seem to work as expected. The connection string for the database service (db_app) works fine on my local machine, but when the IED attempts to start the Docker Compose containers, all containers that rely on the database appear to be unable to locate the db_app host.   This same Compose file works perfectly on my local machine, so it's not an issue with its configuration.   That  is some of log errors   {"log":"Unhandled exception.
