lesson 6：ConnectTimeoutError: Connect Timeout Error

[BBTDR]

When invoking the verify function, an error occurs showing"ConnectTimeoutError: Connect Timeout Error." Here are the error details:

ConnectTimeoutError: Connect Timeout Error
    at onConnectTimeout (/root/hh-fcc/hardhat-simple-storage-fcc/node_modules/undici/lib/core/connect.js:182:24)
    at /root/hh-fcc/hardhat-simple-storage-fcc/node_modules/undici/lib/core/connect.js:129:46
    at Immediate._onImmediate (/root/hh-fcc/hardhat-simple-storage-fcc/node_modules/undici/lib/core/connect.js:170:9)
    at processImmediate (node:internal/timers:476:21) {
  code: 'UND_ERR_CONNECT_TIMEOUT'
}

When I attempted to verify the contract using the terminal, I commented out the section of the code that calls the verify function. However, a new error has emerged. Here is the new error:

Error: could not decode result data (value="0x", info={ "method": "retrieve", "signature": "retrieve()" }, code=BAD_DATA, version=6.7.1)

  code: 'BAD_DATA',

}
error Command failed with exit code 1.

I'm unsure how to resolve this issue and would appreciate any assistance I can get.
For better understanding, here are some of my code files:
depoly.js

// imports
const { ethers, run, network } = require("hardhat");
// const { TASK_COMPILE_SOLIDITY } = require("hardhat/builtin-tasks/task-names");
require("dotenv").config();

// async main
async function main() {
  const ETHERSCAN_API_KEY = process.env.ETHERSCAN_API_KEY;
  const ACCOUNT_ADDRESS = "0x1dc58ac1B682110189265a74779C0dABd3667375";
  const SimpleStorageFactory = await ethers.getContractFactory("SimpleStorage");
  console.log("deploying...");
  const SimpleStorage = await SimpleStorageFactory.deploy();
  console.log("Contract address");
  console.log(SimpleStorage.target);

  //定义网络chainID，并且在API存在的情况下执行====》如果我们在sepolia测试网下，且API存在，则执行
  if (network.config.chainId === 11155111 && process.env.ETHERSCAN_API_KEY) {
    await SimpleStorage.deploymentTransaction().wait(6); //等待六个区块验证
    console.log("waiting");
    await verify(SimpleStorage.target, [ACCOUNT_ADDRESS]);
  }
  // 显示网络信息
  console.log(network.config.chainId);
  // 调用合约函数
  const currentValue = await SimpleStorage.retrieve();
  console.log(`current Value is:${currentValue}`);
  // 更新数据
  const transactionResponse = await SimpleStorage.store(7);
  await transactionResponse.wait(1); //等待一个区块验证
  const updatedValue = await SimpleStorage.retrieve();
  console.log(`updated value is:${updatedValue}`);
}

// 验证合约
async function verify(contractAddress, args) {
  console.log("verifying contract...");
  try {
    console.log("waiting22222");
    await run("verify:verify", {
      address: contractAddress,
      constructorArguements: args,
    });
  } catch (e) {
    //防止合约已被验证
    if (e.message.toLowerCase().includes("already verified")) {
      console.log("already verified!");
    } else {
      console.log(e);
    }
  }
}

// main
main()
  .then(() => process.exit(0))
  .catch((error) => {
    console.error(error);
    process.exit(1);
  });

hardhat.config.js

require("@nomicfoundation/hardhat-toolbox");
require("dotenv").config();
// require("@nomiclabs/hardhat-etherscan");
// require("@nomicfoundation/hardhat-verify");

/** @type import('hardhat/config').HardhatUserConfig */
const SEPOLIA_RPC_URL = process.env.SEPOLIA_RPC_URL;
const PRIVATE_KEY = process.env.PRIVATE_KEY;
const ETHERSCAN_API_KEY = process.env.ETHERSCAN_API_KEY;
console.log(process.env.PRIVATE_KEY);
console.log(process.env.SEPOLIA_RPC_URL);
module.exports = {
  //默认网址为hardhat，在networks里面添加其他测试网
  defaultNetwork: "hardhat",

  networks: {
    hardhat: {},
    sepolia: {
      url: SEPOLIA_RPC_URL,
      accounts: [PRIVATE_KEY],
      chainId: 11155111,
    },
  },
  solidity: "0.8.19",
  etherscan: {
    apiKey: ETHERSCAN_API_KEY,
  },
};

I attempted to verify the contract by entering the command line in the terminal, but I am still encountering the same error. Below are the commands I entered and the resulting output. I feel quite confused and would greatly appreciate someone's assistance in resolving this issue.
Command input:

root@DESKTOP-LHC8M03:~/hh-fcc/hardhat-simple-storage-fcc# yarn hardhat verify --network sepolia 0x5D9E9aE0B283A18025751BF444f01428D7b8E3E4 0x1dc58ac1B682110189265a74779C0dABd3667375

Output:

yarn run v1.22.19
$ /root/hh-fcc/hardhat-simple-storage-fcc/node_modules/.bin/hardhat verify --network sepolia

I hope this additional information helps in understanding the problem.

• The second parameter, you have to pass args (constructor arguments) not address the contract when calling verify function, like this
  await verify(SimpleStorage.target, []);
• And there is another way to deploy contract using hardhat-toolbox,
• In this case, just run the command without passing any parameters

yarn hardhat run [scripts/deploy.js] --network sepolia

Transferring addresses is one solution I found on this website, but it didn't solve my problem. I have also attempted not passing any parameters, but I still encounter the same timeout error.

Try open SEPOLIA_RPC_URL in browser to check your url

[theirrationalone]

A typo is there....

constructorArguements: args, // ❌
constructorArguments: args, // ✅ 😉

try {
console.log("waiting22222");
await run("verify:verify", {
    address: contractAddress,
    constructorArguements: args,    //  ❌
});

Another prominent thing...

networks: {
    hardhat: {
        url: "http://127.0.0.1:8545    //😉
    },
    sepolia: {
    url: SEPOLIA_RPC_URL,
    accounts: [PRIVATE_KEY],
    chainId: 11155111,
    blockConfirmations: 5    // 😉 prominent to mine blocks. 
    },
}
