Websocket connection doesn't work with redis cluster

I'm trying to establish a websocket connection but it doesn't seem to work due to my redis server which is a cluster from elasticache.

Here are the logs:

I thought this was a dns issue with my redis cluster but nslookup for the cluster endpoint worked fine.

CHANNEL_LAYERS = {
    "default": {
        "BACKEND": "channels_redis.core.RedisChannelLayer",
        "CONFIG": {
            "hosts": [("rediss://clustercfg.rediscluster.m0rn9y.use1.cache.amazonaws.com", 6379)],
        },
    },
}
