Thank you for your reply … this dosnt work too … Same problem 
EDIT: My Code -
var tmi = require(‘tmi.js’);
var options = {
options: {
debug: true
},
connection: {
cluster: “aws”,
reconnect: true
},
identity: {
username: “BOT_NAME”,
password: “oauth:MY_PW”
},
channels: [“test_user”]
};
var client = new tmi.client(options);
client.connect();
client.on(“ban”, function (channel, username, reason) {
console.log("User " + username + " banned in " + channel + ". (Reason: " + reason + “)”);
});
Output: User test_123 banned in test_user. (Reason: null)
