Since I updated my Masternode to the latest version, I'm cannot start my Masternode anymore:


bitcoin2-cli --datadir=/wallet/ masternode list-conf
[
  {
    "alias": "mn",
    "address": ":",
    "privateKey": "",
    "txHash": "",
    "outputIndex": "0",
    "status": "MISSING"
  }
]

Any idea what's wrong with my mn?
