[h-ameer0007]

guys i have been looking through the discussion form but couldn't fund an answer for this specific issue i am facing
here is the error log

 Deploying, Please wait...
JsonRpcProvider failed to startup; retry in 1s
Error: connect ECONNREFUSED 127.0.0.1:7545
    at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1157:16) {

}
/home/ameer/hh-fcc/ethers-simple-storage/deploy.js:25
    ProcessingInstruction.exit();
    ^

    at /home/ameer/hh-fcc/ethers-simple-storage/deploy.js:25:5
    at processTicksAndRejections (node:internal/process/task_queues:96:5)

and here is my depoly.js code

 const ethers = require("ethers");
const fs = require("fs-extra");
//http://127.0.0.1:7545
async function main() {
  const provider = new ethers.JsonRpcProvider("http://127.0.0.1:7545");
  const wallet = new ethers.Wallet(
    "0x1b80997f761253915c6258d9f066440b0b8b416f91b4bed2cadff5fd989f36e6",
    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();
  console.log(contract);
}

main()
  .then(() => ProcessingInstruction.exit(0))
  .catch((error) => {
    console.error(error);
    ProcessingInstruction.exit();
  });

  .catch((error) => {

@h-ameer0007 Check your ganache connection.

[vishwa7dcap786]

change your port number in server setting in ganache and restart the ganache

[h-ameer0007]

STILL THE SAME OUTSOME!!!!

[husna3249]

• keep ubuntu open and type ganache-cli

• make sure you also change the url to the updated port number

• const provider = new ethers.JsonRpcProvider("http://127.0.0.1:7545");

• const provider = new ethers.JsonRpcProvider("http://127.0.0.1:8545");

[SagarRuhela]

Go to Ganache setting and then select server and change Hostname to vEthernet(WSL) then save and restart the Ganache
and change the URL in your code to new Url it will solve your problem

This solved issues I was having. If using the Windows version of Ganache it by default binds to the local loopback address 127.0.0.1. If you are using Visual Studio Code the WSL bash shell it cannot access the loopback address (until changes are made in the server section on Ganache), hence this error.
