Kibana POST 403 (forbidden) on create index

You are giving very little information and all one liners. More logs, screenshots should help. However, can you try

POST .kibana/_search
{
  "query": {
    "term": {
      "type": {
        "value": "index-pattern"
      }
    }
  }
}

see if it's there in the search results. Then try your steps again but with dev tools open and note any errors.

Hope this helps,

Cheers
