Smartnode wont start



I am unable to start my Smartnode for some time now. I get the following error on the server:

smartadmin@smartcashnode01:~$ smartcash-cli smartnode status
  "service": "",
  "status": "Not capable smartnode: Smartnode not in smartnode list"

And i have attached an image to show the response on the Wallet.

Any help greatly appreciated.



Error message are clearly , please double check your smartnode.conf and make sure IP, port, output are correct. Also please wait VPS and Local wallet are fully synced before start smartnode


Actually Could nto allocate outpoint does not point to any specific error. The server was running fine for months and there has been no change to the wallet.

Does this error point to some specific problem?

Any help guidance appreciated.
