Error exception status 200 on applying for Original degree at jntuh portal .

I'm unable to understand why I'm getting this error after uploading pc and photo right at payment gateway option, whatsoever which device i try from at the very last step payment is gimmicky . Not any one of t wallet or sbi mops is working, but to my surprise if I am not uploading both files it is working fine . I had also cross checked whether the files were incompatible but it was no fault.
