Hello!

No, there wont be any problem. Make sure that you did not enter registration number which is completely different from roll number. Roll number is a 8 digit number (completely numbers, no special characters and alphabets).This roll number will be below your name in the marksheet. Even while uploading make sure you upload the officially verified certificate. Incase if you are uploading digilocker certificate don't share the screen shot instead download the original certificate and upload it. ALL THE BEST. Hope the answer was helpful.

Thank You
