I'm trying to set up weaviate on railway. Since their migration to the v4 client, I cannot instantiate a python client. This seems to be because it requires both a grpc and an http host and port.

import weaviate
client = weaviate.connect_to_custom( http_host=, http_port=, http_secure=True, grpc_host=, grpc_port=, grpc_secure=True, )

This times out. I've tried using a TCP proxy as per the advice here. https://www.answeroverflow.com/m/1178132082157961367

But it only exposes one host and port, so I can't figure out how to provide both http and grpc ports. Weaviate enforces that they be different.
