Lesson 6 Networks in Hardhat: Connect timeout error

[Rishi860]

I was deploying my SimpleStorage contract to a test net using hardhat networks.

hardhat.config.js file

const GOERLI_RPC_URL = process.env.GOERLI_RPC_URL;
const PRIVATE_KEY = process.env.PRIVATE_KEY;

module.exports = {
  solidity: "0.8.8",
  networks: {
    goerli: {
      url: GOERLI_RPC_URL,
      accounts: [PRIVATE_KEY],
    },
  },
};

deploy.js file

async function main() {
  console.log("inside main function: deploy.js");
  const SimpleStorageFactory = await ethers.getContractFactory("SimpleStorage");
  console.log("Deploying Contract...");
  const simpleStorage = await SimpleStorageFactory.deploy();
  await simpleStorage.deployed();
  console.log(`Contract deployed at address: ${simpleStorage.address}`);
}

terminal output: Error

how can I solve this?

My issue was the same, I tried using different networks with Infura and Alchemy, but no luck. Currently, Moralis works.

Thank you for the help, Infura worked for me!
But what could be the reason for this error?

[vaasanthk]

I have no idea, it's been happening for quite some time now, these servers stop responding without a reason. I've been switching platforms to find out which one works. Sometimes, none of them work, and my only concern is whether they will cease to support test-net.
