JWT Token Expired issue when using Twilio JS Client API

I'm creating a webb application where one can click on a number and dial from the browser.

I'm using the Twilio JS Client API and a Django back end to generate capability tokens. I'm using this Python Helper Library.

Everything seems to be working just fine but as soon as I'm trying to make a call I get a error on my client:

Uncaught Twilio.Exception: 31205: [object Object] twilio.min.js:45

WebSocket is already in CLOSING or CLOSED state.

Error 31205 is a JWT token expired error which is strange as the token has had a lifetime of 1 minute at most when I click-to-dial.

This is my view method in Django which generates a nice capability token:

def dialer(req, phone_number):
    capability = TwilioCapability(settings.TWILIO_ACCOUNT_SID,
                                  settings.TWILIO_AUTH_TOKEN)
    # allow outgoing voice
    capability.allow_client_outgoing(settings.TWILIO_APP_SID)
    profile = user_models.UserProfile.objects.get(user=req.user)
    v = {'capability_token': capability.generate(expires=600),
         'phone_number': phone_number, 'user': req.user, 
         'caller_id': profile.user_phone}
    return shortcuts.render_to_response('dialer.html', v)

And this is the JavaScript in my dialer.html:

Twilio.Device.setup('{{capability_token}}'); 
Twilio.Device.ready( function(device) {
   console.log('Device ready...');
}); 
Twilio.Device.connect({
   CallerId:'{{caller_id}}',
   PhoneNumber: '{{phone_number}}'
});
$('#hang-up').click( function() {
   Twilio.Device.disconnectAll();
});

Any ideas on why I'm getting this error? The Twilio documentation says that the capability_token has a lifetime of one hour as default.

Thanks!

PS. I made the exact same application using Node.js as back end and that works great :)

SOLVED IT!

So there isn't any issues with code. The problem was my Virtual Machine that had the wrong date/time settings.

So, make sure that is correct when your trying to retrieve capability tokens from Twilio :)
