Deploy from Remix not in Etherscan - NFT Bulk Upload Tutorial

I am trying to deploy from Remix to the Rinkeby test network but the contract does not show in Rinkeby etherscan. I am not sure how to debug from here. I get a transaction hash every time but it is not making it on chain.
Can anyone recommend troubleshooting tools or guides to figure this out?

maybe you didn’t select to use current injected web3 in remix on deploy, metamask should popup when deploying on rinkeby to sign that transaction

Yes I did select that and Metamask did appear. I sign the transaction and then get a hash# every time. The problem is that when I paste the hash in Etherscan (Rinkeby), there is no transaction showing.
