Check the mobile number linked to your Aadhar, as OTP is received on mobile no. linked to Aadhar.
There is time limit fixed to submit the OTP for verification, if not submitted during that time, it lapses.
We have not found much problem, with Aadhar OTP (except during some busy hours).
So, try again after the mobile no. check; its working fine.
