How to deploy smart contract using truffle and ropsten with Metamask account

Question

I have this error when i use :"truffle migrate --network ropsten"

This is my truffle-config.js:

What I want to do is deploy my smart contracts using the same account (address) that I entered on Metamask. Why do I get another address when I deploy? How can I go about using the specific one of Metamask that Ropsten uses?

EDIT I managed to do the migration using, on Metamask, the address indicated in the console and uploading ETH. The problem remains as the account I want to use must be that of a hypothetical user who wants to access my dApp and sign contracts and not the one that Truffle provides you.

It looks fine, my guess is that there's an issue with rpcURL.

1. Double check you're connecting to the correct URL.
2. Try using https://ropsten.infura.io/, maybe there's an error with your node.
3. Try replacing the ropsten definition with this -

    ropsten: {
      // must be a thunk, otherwise truffle commands may hang in CI
      provider: () =>
        new HDWalletProvider(mnemonic, "https://ropsten.infura.io/"),
      network_id: '3',
    }
