Hi @abhishek2k11, 

Has this issue started only in the last 4 days, or is this an account you haven't accessed for a long time? I’m wondering if it’s because you may have reached a limit, which is certainly the case for the free edition. 

Unless you have any notebooks or data that you can't afford to lose, I recommend signing up with a new email address for convenience. If you would like to keep your current account, consider submitting a support request to have the issue resolved by the appropriate team. To do this, click your initials in the top right corner of your login page for the free edition and select "Send Feedback." You will then see an option to raise a ticket or contact support.

Hope this helps!

If this answer resolves your question, could you mark it as “Accept as Solution”? That helps other users quickly find the correct fix.

Regards,
