So we restarted our Elastic-Cluster last week, today i noticed that there are a lot unassigned Shards.
I thought my colleagues forgot to turn Shard - Allocation back on, which i can confirm by now.
I now i have to change it back in Order to get my Unassigned Shards away. But now if i try to do
```
curl -XPUT "http://YY.XX.ZZZ.YXZ:9200/_cluster/settings" -d '{
"transient" : {
"cluster.routing.allocation.enable" : "all"
}
}'
```
i get the following Error : {"error":"Content-Type header [application/x-www-form-urlencoded] is not supported","status":406}
Thanks for you help in advance guys!

You need to add:
```
-H 'Content-Type: application/json'
```
