Hello Aspirant,

Don't worry for this issue because this is nothing but a network error of time delay this is happening with you because you might left that window opened for very long time and due to inactivity and security reasons these secured sites  throws the Session Time out error. So what you have to do is just close all your tabs on the search engine whichever you are using and then open your searching engine and again make login to your application form of JEE-Main 2021 using the same login credentials which you have received on your e-mail and SMS and then retry it without wasting any time because now the NTA portal has identified your system as unsecured system (not to fear of anything because this is normal). Now if you will try to fill new application form from same Mobile number and e-mail ID then it will not allow you to create the another one because from one phone number and one e-mail ID only one application form is allowed to filled.

I hope this information helps you and your problem is resolved if not then please ask me in comments section, I will help you out with further process.
