Not able to connect to VNC | Closing connection with error: Error: not opened

I am having above error when connecting to gucamole .I am trying to connect using vnc protcol and flowing is my setup

#!/usr/bin/env node

const GuacamoleLite = require('guacamole-lite');

const websocketOptions = {
    port: 8080 // we will accept connections to this port
};

const guacdOptions = {
    port: 4822 // port of guacd
};

const clientOptions = {
    log: {
        verbose: true
    },
    crypt: {
        cypher: 'AES-256-CBC',
        key: 'MySuperSecretKeyForParamsToken12'
    }
};

const guacServer = new GuacamoleLite(websocketOptions, guacdOptions, clientOptions);

To generate the Token I am using a script -

const crypto = require('crypto');

const clientOptions = {
    cypher: 'AES-256-CBC',
    key: 'MySuperSecretKeyForParamsToken12'
}

const encrypt = (value) => {
    const iv = crypto.randomBytes(16);
    const cipher = crypto.createCipheriv(clientOptions.cypher, clientOptions.key, iv);

    let crypted = cipher.update(JSON.stringify(value), 'utf8', 'base64');
    crypted += cipher.final('base64');

    const data = {
        iv: iv.toString('base64'),
        value: crypted
    };

    return new Buffer(JSON.stringify(data)).toString('base64');
};

console.log("Token : " + encrypt({
    "connection": {
        "type": "vnc",
        "settings": {
            "hostname": "192.168.43.158",
            "port": "5900",
            "username": "pawan",
            "password": "pawan"           
        }
    }
}));

And my client side app looks like this --
