National Payments Corporation of India [NPCI] — Cant Use the npci mapper site, It says TECHNICAL EXCEPTION message

Hi, I tried the uidai bank mapper site, after entering the aadhar number and the OTP, it says TECHNICAL EXCEPTION message, I tried many times but I get the same error, again and again, I even tried at times when there is less traffic on site, but still, the same error pops up.
