Goerli testnet deploy error

[zeledorka]

Hi everyone,

Have anyone encountered the following error while trying to deploy ERC721 contract to goerli?

failed to get chainId, falling back on net_version...
Error HH110: Invalid JSON-RPC response received: {"error":"unauthorized"}

It works without a problem on rinkeby.

My hardhat.config.js:

require("@nomiclabs/hardhat-waffle")
require("@nomiclabs/hardhat-etherscan")
require("hardhat-deploy")
require("solidity-coverage")
require("hardhat-gas-reporter")
require("hardhat-contract-sizer")
require("dotenv").config()

/**
 * @type import('hardhat/config').HardhatUserConfig
 */

const RINKEBY_RPC_URL = process.env.RINKEBY_RPC_URL
const PRIVATE_KEY = process.env.PRIVATE_KEY
const ETHERSCAN_API_KEY = process.env.ETHERSCAN_API_KEY
const GOERLI_RPC_URL = process.env.GOERLI_RPC_URL

module.exports = {
    defaultNetwork: "hardhat",
    networks: {
        hardhat: {
            chainId: 31337,
            blockConfirmations: 1,
        },
        localhost: {
            chainId: 31337,
        },
        rinkeby: {
            chainId: 4,
            blockConfirmations: 6,
            url: RINKEBY_RPC_URL,
            accounts: [PRIVATE_KEY],
        },
        goerli: {
            url: GOERLI_RPC_URL,
            accounts: [`0x${PRIVATE_KEY}`],
            chainId: 5,
            blockConfirmations: 6,
        }
    },
    solidity: {
      compilers: [
        { version: "0.8.7"},
        { version: "0.6.12"},
        { version: "0.4.19"},
        { version: "0.8.8"}
      ]
    },
    namedAccounts: {
        deployer: {
            default: 0, // here this will by default take the first account as deployer
            1: 0, // similarly on mainnet it will take the first account as deployer. Note though that depending on how hardhat network are configured, the account 0 on one network can be different than on another
        },
        player: {
            default: 1,
        },
    },
    gasReporter: {
        enabled: false,
        currency: "USD",
        outputFile: "gas-report.txt",
        noColors: true,
        // coinmarketcap: COINMARKETCAP_API_KEY,
        token: "MATIC",
    },
    mocha: {
        timeout: 300000,
    },
    etherscan: {
        // yarn hardhat verify --network <NETWORK> <CONTRACT_ADDRESS> <CONSTRUCTOR_PARAMETERS>
        apiKey: {
            rinkeby: ETHERSCAN_API_KEY,
        },
    },
}

Thanks for the help!

@zeledorka : Check you Goerli RPC URL , I think that's why it is causing the error!

If it works correctly on Rinkeby, there is no issue whatsoever with the logic besides an error which relates to Goerli (e.g. incorrect info. in hardhat.config, .env etc.)

If there are no such issues whatsoever, do not worry--if you really want to use Goerli, try w/ a different provider; if it still persists, it is certainly a Goerli-specific issue and not a provider-specific issue.
