Error in hardhat config file

Question

I am having an issue with smart contract deployment using hardhat. I don't see where is the error coming from. I have defined the .env file with values and also correctly called those values using process.env here is my hardhat.config file :

require("@nomicfoundation/hardhat-toolbox");

require('dotenv').config();

/** @type import('hardhat/config').HardhatUserConfig */
module.exports = {
  defaultNetwork: "goerli",
  paths: {
    artifacts: "./artifacts",

  },

  networks: {
    goerli: {
      chainId: 5,
    },
    goerli: {
      url: process.env.API_URL ,
      accounts: [process.env.PRIVATE_KEY] ,
    }
  },
  solidity: "0.8.0",
};

I believe what is happening is that the specific node you are trying to use to access the blockchain could be down or not available.... But before you assume that, try running whatever task you are doing using your local node and if it works then your online node must be down In my case, I got the error

Error: could not detect network (event="noNetwork", code=NETWORK_ERROR, version=providers/5.7.2)

and I solved it by changing the goerli_rpc_url in my environment variable from an alchemy supplied one to one from infuria from

rpc_url=https://eth-goerli.g.alchemy.com/v2/2xAXsdfsadkflasdfaskdfhrandom

to

rpc_url=https://goerli.infura.io/v3/randomsdfkalsdfjrandom
