Status check not working on one site

[iburrows]

Hi, the monitor is working well for all of the endpoints except for one. Even though the endpoint returns 200.
It is for a Hashicorp Vault instance and returns:

{
  "initialized": true,
  "sealed": false,
  "standby": false,
  "performance_standby": false,
  "replication_performance_mode": "disabled",
  "replication_dr_mode": "disabled",
  "server_time_utc": 1588661588,
  "version": "1.4.0",
  "cluster_name": "vault-cluster",
  "cluster_id": "123456qwqw-sdfs"
}

The monitor always shows that part of the requests are filling the threshold.
This is my config file:

  # cachet api token
  token: TOKEN
