ioredis: [Cluster] Failed to refresh slots cache

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 usesioredis) 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.
