laravel 10 sail - connection refused when attempting connecting to one of 2 containerised apps

so i need to have multiple containerised microservices running and talking to each other. For this i have a main microservice which does authentication and management of a users account. that app uses breeze for internal auth and passport to provide a oauth server to the other microservices. im using laravel sail to have these apps running in containers.

my issue is that i am only able to connect to the auth service app and the other app im currently building refuses connections to it and when run without sail refuses connections to its own css file. this is my first time using sail and docker properly coming from just using laragon to build stuff.
