Redirecting to login page

I wasted my 2 days trying for revaluation

I wrote the whole reasons 3 times and each time after clicking on save and preview it's redirecting me to login page and when I login again all gone

Nothing is working in trying from 2nd of June late night, i didn't sleep today..just finished rewriting the whole thing and again it vanished bruh I'm tired now...total 40 questions....around 35-40 marks...it neither accepts copy paste from draft nor I can save each question after writting the reasonn

I have re-neet on 21 now I have to waste time on such things 😭

If I call on cbse helpline they don't pick up

If someone facing similar issues plz help
