Rinkeby address for my would-be ERC 721 contract is not whitelisted. How can this be fixed?

[villarode]

What exactly can it be? Address ..... is not whitelisted?? I am assuming that .... is the rinkeby.etherscan.io address of my would-be ERC 721 contract? How can this be fixed? Cheers in advance!)

$ yarn truffle deploy --network rinkeby
