Am Getting this error while deploying contract from my loca.

[taruntailor7]

This is my code.

const ethers = require("ethers");
const fs = require("fs-extra");

async function main() {
// compile them in our code
// compile them separately
// http://127.0.0.1:7545
const provider = new ethers.JsonRpcProvider("http://127.0.0.1:7545");
const wallet = new ethers.Wallet(
"0x358dbca4e4bfc0bb7b9a4cfdee7c8dea8ec4c0c4a87fbc724867cb9d4b064575",
provider
);
const abi = fs.readFileSync("./SimpleStorage_sol_SimpleStorage.abi", "utf8");
const binary = fs.readFileSync("./SimpleStorage_sol_SimpleStorage.bin", "utf8");

const contractFactory = new ethers.ContractFactory(abi, binary, wallet);
console.log("Deploying, please wait...");
const contract = await contractFactory.deploy(); // STOP here! Wait for the contract to be deployed
console.log(contract, "Contract"); 

}

main()
.then(()=> PerformanceMeasure.exit(0))
.catch((error)=> {
console.log(error, "Error");
process.exit(1);
})

and am getting this error

JsonRpcProvider failed to detect network and cannot start up; retry in 1s (perhaps the URL is wrong or the node is not started)
Error: connect ECONNREFUSED 127.0.0.1:7545

In my case

I use the "WSL (UBUNTU) in my "VS Code", therfore to solve this problem.

I went to settings after => to server tab => and changed my hostname to ".... (WSL (Hyper-V firewall))
