qdrant-client: qdrant_client.http.exceptions.ResponseHandlingException: [Errno -2] Name or service not known

Hello,

I have a local setup as follows:

database = QdrantClient(host=settings().HOST, port=6333, api_key=settings().QDRANT_API)

where HOST and QDRANT are defined in a dotenv file where HOST points to a QDRANT cloud instance ‘https://.*.aws.cloud.qdrant.io’. This works great when initializing the db locally using fastAPI with:

uvicorn main:app --reload 

As soon as I try deploying on fly.io I get the following error:
