_update_by_query is very slow (version 7.3 elastic cloud)

when I use this query from dev tools in Kibana

POST some_index/_update_by_query?conflicts=proceed
  "script": {
    "source": "ctx._source.view_count = 0",
    "lang": "painless"

it will return

  "ok": false,
  "message": "backend closed connection"

We have about 300,000 records which isn't much.

How should I solve this problem?
