Please try later," read the error message on the portal that some users shared on Twitter. Earlier today, the National Health Authority said that they expected more than 10 million users to register on the portal and that the system will be able to take the load.

"On many days, we have had around 5 mn people registering in a day. We expect more than double that number today. We think our system will be able to take the load when registrations open today," said RS Sharma, CEO of, National Health Authority.

The registration window opened at 4 pm for all people above the age of 18 years. They will be able to book an appointment to get vaccinated against COVID-19 through the portal. Meanwhile, the Aarogya Setu app, which also has the facility to register for vaccination also faced issues as many users were not able to book appointments.
