Enps — NPS Payment issue

Dear Sir,

I updated my details and uploaded the required documents. Then I tried to make payment but got stuck at the payment gateway. Now i am trying to complete the pending registration using my acknowledgement id and date, but i am getting following error

"registration against this acknowledgement id is pending for confirmation from the payment gateway. Please try again after some time."

Error- ''The response from the Payment Gateway for the payment attempt against this acknowledgement number is awaited. We request you to wait for the re-try of payment process for registration in NPS #''
Please help to slove this issue
