Guru Gobind Singh Indraprastha University — cannot login

Website:

www.ipu.ac.in

I have already paid my participation fee and registered for the online counselling as per the university but, i am not able to login to the online counselling portal right now using my registeration details. Even though i'm providing the correct details, it shows a pop up that either the cet roll no. Is incorrect or the password. I even tried changing the password and logging in but still it shows the same pop up.
Need some help, please.
