Issue

I followed tutorial to create a very simple token and crowdsale contract with Truffle and zeppelin-solidity. I managed to successfully migrate to Ganache locally, but when I tried to migrate to ropsten I encountered the following error:

Error encountered, bailing. Network state unknown. Review successful transactions manually.

I researched online and some answers said that this happened because of trying to deploy abstract contract to the testnet. But it seems this is not the case for me.

Steps to Reproduce

1. Clone this repository https://github.com/chenwenwen11/TestCrowdsale.git
2. terminal run: npm install -g truffle
3. cd to the TestCrowdsale
4. terminal run: npm install zeppelin-solidity
5. terminal run: npm install truffle-hdwallet-provider
6. terminal run: truffle compile
7. terminal run: truffle migrate --network ropsten

Expected Behavior

Contracts are successfully migrated to Ropsten testnet

Actual Results

Environment

• Operating System: macOS High Sierra
• Ethereum client: web3
• Truffle version (truffle version): v4.1.3
• node version (node --version): v9.8.0
• npm version (npm --version): 5.6.0
• solidity version: v0.4.19
• zeppelin-solidity version: 1.7.0
• Ganache version: 1.0.2

@chenwenwen11 It looks like you are using a Zeppelin contract called TimedCrowdsale which has a constructor that checks to make sure the crowdsale start time value is greater than the chain value now.

function TimedCrowdsale(uint256 _openingTime, uint256 _closingTime) public {
    require(_openingTime >= now);
    require(_closingTime >= _openingTime);

    openingTime = _openingTime;
    closingTime = _closingTime;

In your migrations you are setting startTime to the current system time. When the contract executes now is later than startTime causing the transaction to fail. Could you try adding some spare time to the line below in your migrations and see if that works?

const startTime = Math.round((new Date(Date.now()).getTime())/1000); // <--- Too soon! 
const endTime = startTime + (86400 * 2); // 30 days;

@chenwenwen11 Etherscan doesn’t automatically recognize an ERC20 compliant contract. You need to transfer some token to another address first.
