NPS — Not able to complete my registration in nps as getting payment gateway issue

Hi Team,
I am not able to complete my pending PRAN registration by logging in nps website An error is displayed as "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#"

Kindly resolve this issue at the earliest as it is on high priority for me at this moment
