Successful deploy the FundMe by script DeployFundMe,but fail to verify

[qingqingjian]

I try to use makefile to deploy and verify FundMe contract on sepolia,the deploy is successful, but verify is failed. Anyone can help with this one? Thanks.

Here is my script:

        address priceFeed = helperConfig
            .getConfigByChainId(block.chainid) 
            .priceFeed;

        vm.startBroadcast();
        FundMe fundMe = new FundMe(priceFeed);
        vm.stopBroadcast();
        return (fundMe, helperConfig);
    }

    function run() external returns (FundMe, HelperConfig) {
        return deployFundMe();
    }
}

        vm.stopBroadcast();

this is error

[qingqingjian]

i use: make deploy-sepolia

[EngrPips]

Yeah that command will run a script, So please show the script it is running.

It seems to work fine for me. Please show your Deployment script

[EngrPips]

From the error you showed above, it seems like your script deployed things correctly, but the issue is with verifying the contract. Have you checked that your etherscan api-key is working correctly?

[yong67]

Quiet similar issue! Seems you are also a China developer by your ID. I guess it's a network issue. How is you going with this problem, bro?

Please don't reveal private-key details publicly like this, I know it might be a dummy account, but don't get into the habit at all.

It is kind of tough to say what the issue could be.

[yong67]

I think it's some kind of network issue. Maybe it's due to I'm doing these in China, I have been numb to these network issue which related to proxy or VPN in mosttime.

sepecific Error partition:

Error: Failed to verify contract: Failed to submit contract verification, payload:

error sending request for url (https://api-sepolia.etherscan.io/api): client error (Connect): tcp connect error: Connection timed out (os error 110): Connection timed out (os error 110)

Anyway, I use manually verification finally. If anyone have problems in dealing with uploding source file with multiple dependencies, kindly try 'forge flatten' to get a integrated file. e.g. as follow:

forge flatten --output FlattenedOut/FundMe.flattened.sol src/FundMe.sol

Awesome, I am glad you figured it out. Keep crushing it!
