Large number of broken miner configs
I have a couple of faulty miners relating to miningpool hub.

MiningPoolHubCOins_Cryptonight7_XXX_CPU.txt
  "pool_list": [
    {
      "pool_address": "us-east.cryptonight-us-east.cryptonight-hub.miningpoolhub.com:20580",
      "wallet_address": "Kettoch.Guardian",
      "pool_password": "x",
      "use_nicehash": true,
      "use_tls": false,
      "tls_fingerprint": "",
      "pool_weight": 1,
      "rig_id": ""
    }

That pool address cannot be pinged and there are others showing the same thing.
