[Cluster] Failed to refresh slots cache

Problem

Hey, I am using this docker image to setup my redis cluster. When I connect via a desktop client (Medis), everything is working fine. When I try to connect deepstream.io (which uses`ioredis`) to the cluster, I get the `Failed to refresh slots cache` error. I know there are other issues with the same error, but none of them provided a solution to solve this problem. The fact that I can connect via my desktop tool and not via `ioredis` is pretty weird.
