Caught exception while handling client http traffic, closing connection

Elastic Stack Elasticsearch

Running into an issue on elastic. Right now elastic is not returning
anything, and this is the only thing that keeps being output to the log
file:

Any ideas on what is happening here?

Update: I tried getting it out of an UNASSIGNED state with no luck

When I try to do a simple count on an index, I get this:
{"count":0,"_shards":"total":1,"successful":0,"failed":1,"failures
":[{"index":"wm_index","shard":0,"reason":"BroadcastShardOperationFailedExc
eption[[wm_index][0] No active shard(s)]"}]}}

And this is what I get when I curl :9200/_cluster/health:
{"cluster_name":"elasticsearch","status":"red","timed_out":false,"number_of_nodes":1,"number_of_data_nodes":1,"active_primary_shards":0,"active_shards":0,"relocating_shards":0,"initializing_shards":0,"unassigned_shards":1}

curl -XPOST 'localhost:9200/_cluster/reroute' -d '{
"commands" : [
{"allocate" : {"index" : "wm_index", "shard" : 0, "node" :
"XKYnqpKeSaG87fHixwyeVQ", "allow_primary" : "true"}}
]
}'

A little more on my index:

index.number_of_shards: 1
index.number_of_replicas: 0

You have a cluster state of "red". There are many reasons.

The exception you show tells us, a client aborted the connection, it is
probably not related to the cause.

Does a node restart help?

I'm also getting this exception, with v2.4.1. Any resolution to this? Here's my stack trace. Right now I don't have anything running except Elasticsearch.
