Students complain of login errors on CBSE re-evaluation portal as it goes live

Several students complained of login errors on CBSE's re-evaluation portal after it went live on June 2, a day later than it was expected to start working. "After entering all the required details correctly, it says 'roll number not found'. What should I do now?" one student said. Students also shared several pictures/videos of 'verification failed/login request expired' issues.
