I have deployed a project on Railway consisting of the following:

Go service via Docker(public)

python service via Docker (fast API) via docker which is an internal service

Minio file sever

PgVector DB

I am able to access the the minio, pgVector db via internal services from the go service properly using Private domains but for some reason the python/fast API service keeps throwing Application failed to respond 502 error. i thought it was an issue in my code but when i make the python/fast API service public and try an access it from my local machine with the same go project everything works smoothly. what could be the issue? this is how i am accessing the python-service the go service: IMAGE_SERVICE="http://${{python-service.RAILWAY_PRIVATE_DOMAIN}}:8080"
