Enps — NPS: payment process for registration in NPS #

Website:

enps.nsdl.com/eNPS/OnlineSubRegPrev.html?appType=main

I registered in NPS 29th Mar 2024 and when the payment page came it did not take the payment even after multiple try. Now every time I am trying to "continue to registration" it is giving me the below 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 #".

FYI: ACK ID Generated: 11585212. I used the razorpay option. Please solve the above issue.
