Trying to deploy Qdrant on Railway with a server connecting to the Qdrant instance through private network. Railway calls the ipv6 address, but it seems like Qdrant doesn't accept ipv6 http connection on its Docker. Railway is just a specific example to replicate this issue, but I believe it's true regardless.

Current Behavior

Connection refused.

Steps to Reproduce

  1. Start a Qdrant template on Railway.
  2. Start a basic server image.
  3. Have the server image try to connect to the instance through the private address.

There just is a connection refused issue.

Expected Behavior

The Qdrant server should accept connections from ipv6.

Possible Solution

The equivalent of the following:

const port = process.env.PORT || 3000;

app.listen(port, '::', () => {
    console.log(`Server listening on [::]${port}`);
});

Context (Environment)

I haven't tested this yet, but I wonder setting service.host to '::' in the config.yaml would do the trick.

https://qdrant.tech/documentation/guides/configuration/

# qdrant/config/config.yaml
service:
  # Host to bind the service on
  # host: 0.0.0.0
  host: '::'

This yaml dictionary value get's handled by qdrant, here, and that seems that could work (based on a separate thread I was reading on working with IPv6 and Rust):

qdrant/src/tonic/mod.rs

Line 157 in 27260ab

SocketAddr::from((settings.service.host.parse::<IpAddr>().unwrap(), grpc_port));

Update: the simplest solution is to set the env variable QDRANT__SERVICE__HOST to :: -- I was able to get this to work on Railway and connect to qdrant over the internal network.
