Canara Bank — error in maulana azad national fellowship

Hi there, i have been awarded maulana azad fellowship this year. While linking my profile on scholarship portal, my nodal officer has uploaded wrong verification cum joining document. So ugc has rejected my data and asked me to relink again. When my nodal officer tries to fill up my data and press the submit page then this unknow error screen displays. My nodal officer is facing this problem since last 20 days. The last date of relinking is 31 december 2019, otherwise my fellowship stands cancelled. Please help me out as how to resolve this problem. Please help me as soon as possible as how to solve this? Please, please, understand my situation. I am sharing the screenshot of error page he incurs while uploading information on canara bank portal.
