Users of CoWIN portal, Aarogya Setu, and UMANG app seem to be facing a peculiar problem. The CoWIN portal displays Generate OTP Failed and USRAUT0018 errors thus preventing citizens from booking their appointment slots for the second dose of the COVID-19 vaccine. The issue seems to be quite widespread as several users have been writing to Dataquest stating of the problem.


“I am also facing the same issue since 5.00 pm today evening, and have been unable to generate OTP. I’ve spoken to customer care, and they said they are working on it as this has started post 1 pm today. Also, the app is showing slots for the second dose but it is not accepting bookings,” said Ashish Jain to Dataquest.

“I am unable to book my second dose of Covaxin due to the error, OTP Failed. No support from 24*7 teams, and the technical team is not picking up the phone or responding. Kindly help,” said another viewer. “I am unable to generate OTP on the Aarogya Setu app and on the CoWIN app. We need to book a slot for the second dose of Covaxin. No technical support from the customer care team” said Neha on a similar note.

“I am facing it since 4 pm today. I think it is happening to those people who have:

  1. Tried again and again with OTP to find and book slots

    2. Have to take Covaxin

    3. Have to take the second dose

    4. May have a beneficiary added to their account

So far I have not found any solution. Please write here if somebody finds any solution or if this gets fixed for them automatically. Please help,” said another viewer.
