Unable to verify Lesson 9

[kadiemq]

When I try deploying the contract I get this error NomicLabsHardhatPluginError: The contract verification failed. Reason: Fail - Unable to verify

Here is the deploy script:

import { ethers, network } from "hardhat";
import { HardhatRuntimeEnvironment } from "hardhat/types";
import { developmentChains, networkConfig } from "../helper-hardhat-config";
import { VRFCoordinatorV2Mock } from "../typechain-types";
import verify from "../utils/verify";

const VRF_SUB_FUND_AMOUNT = ethers.utils.parseEther("2");

module.exports = async ({ getNamedAccounts, deployments }: HardhatRuntimeEnvironment) => {
	const { deploy, log } = deployments;
	const { deployer } = await getNamedAccounts();
	const chainId = network.config.chainId;
	let vrfCoordinatorV2Address: string, subscriptionId, vrfCoordinatorV2Mock: VRFCoordinatorV2Mock;

	if (developmentChains.includes(network.name)) {
		vrfCoordinatorV2Mock = await ethers.getContract("VRFCoordinatorV2Mock");
		vrfCoordinatorV2Address = vrfCoordinatorV2Mock.address;
		const txResponse = await vrfCoordinatorV2Mock.createSubscription();
		const txreceipt = await txResponse.wait();
		subscriptionId = txreceipt.events![0].args!.subId;

		await vrfCoordinatorV2Mock.fundSubscription(subscriptionId, VRF_SUB_FUND_AMOUNT);
	} else {
		vrfCoordinatorV2Address = networkConfig[chainId!]["vrfCoordinatorV2"]!;
		subscriptionId = networkConfig[chainId!]["subscriptionId"];
	}

	log("Deploying Raffle contract...");

	const entranceFee = networkConfig[chainId!]["entranceFee"];
	const keyHash = networkConfig[chainId!]["keyHash"];
	const callbackGasLimit = networkConfig[chainId!]["callbackGasLimit"];
	const interval = networkConfig[chainId!]["interval"];

	const args = [vrfCoordinatorV2Address, entranceFee, keyHash, subscriptionId, callbackGasLimit, interval];

	const Raffle = await deploy("Raffle", {
		from: deployer,
		args: args,
		log: true,
		waitConfirmations: networkConfig[chainId as keyof typeof networkConfig]["blockConfirmations"] || 1,
	});

	if (developmentChains.includes(network.name)) {
		await vrfCoordinatorV2Mock!.addConsumer(subscriptionId, Raffle.address);
	}

	if (!developmentChains.includes(network.name)) {
		await verify(Raffle.address, args);
	}
	log("---------------------------------------------------------");
};

module.exports.tags = ["all", "raffle"];

Here is verify script

import { run } from "hardhat";

const verify = async (contractAddress: string, args: any[]) => {
	console.log("Verifying contract...");
	try {
		await run("verify:verify", {
			address: contractAddress,
			constructorArguments: args,
		});
	} catch (e: any) {
		if (e.message.toLowerCase().includes("already verified")) {
			console.log("Already verified!");
		} else {
			console.log(e);
		}
	}
};

export default verify;
