Resque worker processed the job but push notification is not sent

[ghost]

Resque.enqueue(APN::Jobs::ResqueNotificationJob, token, opts) is being called and a job is being scheduled whenever i execute a code APN.notify_async(token, opts) from my rails application in development environment. This job is successfully getting processed with no failure as shown at url /resque/stats/resque
But the notification is not being pushed and no output is logged at 'logs/apn_sender.log'.

Then i tried to send push notification directly from rails console by calling: APN::Jobs::ResqueNotificationJob.perform(token, opts)
This do send push notification.
