You have too many shards in your cluster and should rethink how you index data in order to reduce this. You can increase the limit, but having lots of small shards is very inefficient and will eventually cause problems which is why this limit was introduced.

I would recommend reading [this blog post](https://www.elastic.co/blog/how-many-shards-should-i-have-in-my-elasticsearch-cluster) for more details. [This post](https://discuss.elastic.co/t/how-do-i-increase-or-reduce-the-shard-count-of-an-existing-index/242704) may also be helpful.
