I have a blazor app running in a docker container(debian image),word_game that I’m trying to scaffold using my postgresql db,postgres_db that is running in another container. Blazor app is running in .NET 8. Both containers are connected to docker network, game-net. When I try to scaffold however, I’m getting nodename nor servname provided, or not known.

ocker-compose.yml: services:
