Unknown account error while deploying dapp on Ropsten testnet

Question

While trying to deploy/migrate a dapp to Ropsten I get the following error:

C:\CrowdBank-master\CrowdBank-master>truffle.cmd migrate --reset --network ropsten
Using network 'ropsten'.

Running migration: 1_initial_migration.js
  Deploying Migrations...
Error encountered, bailing. Network state unknown. Review successful transactions manually.
Unknown address - unable to sign transaction for this address: "0x94e1E6DbEf0936d494B7B23C47F80dfA195e28Fa"

I have created the above address (0x94e1E6DbEf0936d494B7B23C47F80dfA195e28Fa) on Metamask, it has a balance of 1 ether.

Here is how my truffle.js file looks like:

// Allows us to use ES6 in our migrations and tests.
var HDWalletProvider = require("truffle-hdwallet-provider");

var infura_apikey = "...";
var mnemonic = "...";
var address = "0x94e1E6DbEf0936d494B7B23C47F80dfA195e28Fa"

module.exports = {
   networks: {
      development: {
        host: 'localhost',
        port: 8545,
        network_id: '*' // Match any network id
      },
      ropsten: {
        provider: function() {
           return new HDWalletProvider(mnemonic, "https://ropsten.infura.io/v3/...")
           },
        network_id: 3,
        from: address,
        gas: 4000000
      }
    }
  }

Below is a link to the project, its designed for localhost, I modified the truffle.js file to deploy it on ropsten. What else do I have to do?

Please help me out on this one.

Answer 1

Well first of all, I think if you are using windows, you should be using `truffle-config.js.

If that doesn't work, try deleting the contracts in build/contracts and recompiling?

Also, in the mneomic you are including does that correspond to the correct account?

I think your address might belong to a different wallet.

When I deploy via infura, I don't include the address because I think infura will assume it is the first address in the wallet, account[0]

 rinkeby: {
  provider: new HDWalletProvider(menomic, "https://rinkeby.infura.io/" + process.env.INFURA_API_KEY),
  network_id: 4
  //gas: 7600000,
  //gasPrice: 100000000000
},
kovan: {
  provider: new HDWalletProvider(menomic, "https://kovan.infura.io/" + process.env.INFURA_API_KEY),
  network_id: 42
  //gas: 7600000,
  //gasPrice: 100000000000
},

Are you following instructions from https://truffleframework.com/tutorials/using-infura-custom-provider?

Answer 2

If you use Infura, you do not need Geth. By the way the issue is resolved now.

Here is the github link: https://github.com/dmajumder4292/crowdp2plending

Deployed it on Digital Ocean, here is the URL: http://139.59.20.121:8080/

Answer 3

Have you synced ropsten to your local machine? Is the address in question unlocked?

You should use probably use geth to deploy contracts to ropsten / mainnet. Can Truffle even do that? I've only ever used it to deploy to Ganache.

Hope this helps.
