Websocket URL to Listen to Smart Contract Events

I have a NodeJs code that has the following lines:
const websocketURL = "ws://65.108.199.222:8548";
const provider = new ethers.providers.WebSocketProvider(websocketURL);

const predictionAbi = require('./abis/predictionAbi.json');
const oracleAbi = require('./abis/oracleAbi.json');
const contractABI = require('./contract.json');
const p_contract = new ethers.Contract(configs._router, predictionAbi, provider);

p_contract.on("StartRound", async (epoch) => {
// Do something
});

The code crashes with a timeout exception.

Help me find another web socket URL that can work.
