Each participant joining in a same conference room individually

Hi

I have deployed a customized jitsi meet. if i try to join a same conference room with multiple participants, both participants can join the meeting but both are in separate meetings individually. Can you help to fix this ?

Atteaching my config,js here

var config = {
// Connection
//

hosts: {
    // XMPP domain.
    domain: 'xx.yy.com',

    // When using authentication, domain for guest users.
    // anonymousdomain: 'guest.example.com',

    // Domain for authenticated users. Defaults to <domain>.
    // authdomain: 'xx.yy.com',

    // Focus component domain. Defaults to focus.<domain>.
    focus: 'focus.xx.yy.com',

    // XMPP MUC domain. FIXME: use XEP-0030 to discover it.
    muc: 'conference.' + subdomain + 'xx.yy.com',
},

// BOSH URL. FIXME: use XEP-0156 to discover it.
bosh: '//xx.yy.com/' + subdir + 'http-bind',

// Websocket URL (XMPP)
// websocket: 'wss://xx.yy.com/' + subdir + 'xmpp-websocket',

// The real JID of focus participant - can be overridden here
// Do not change username - FIXME: Make focus username configurable
// https://github.com/jitsi/jitsi-meet/issues/7376

have also updated in webpack.config.js.
