Applying for the University of Nigeria, Nsukka (UNN) can feel exciting but also overwhelming. Every year, many applicants run into frustrating problems like slow website speed, locked forms after payment, and missing support. If you’re currently stuck, maybe you’ve paid but can’t continue, this guide will walk you through exactly what to do.
No stress. No confusion. Just step-by-step instructions that work, even when the portal shows “Submission Failed” or payment does not reflect.
Why the UNN Portal Fails Every Year
You’re not alone. During peak admission season, the UNN portal often crashes due to a high number of users trying to access it at once. These common complaints show up every year:
- “I paid but the form is still locked.”
- “It keeps saying submission failed.”
- “The site is too slow, I can’t even log in.”
- “I uploaded my documents but it says ‘try again.’”
- “I don’t know who to contact for help.”
This guide is created to help you solve these exact problems — with clear steps and no guesswork.
Step-by-Step: What To Do If You’ve Paid But Can’t Proceed
1. Confirm Your Payment
- Check your bank app, email, or Remita account.
- Look for a successful payment status and copy your RRR (Remita Retrieval Reference).
- Screenshot your payment proof and save it.
2. Clear Your Browser Cache
- Open your browser (preferably Chrome or Firefox).
- Go to Settings > Privacy > Clear Browsing Data.
- Select “Cached images and files” only.
- Restart your browser afterward.
3. Change Device or Browser
- Mobile phones sometimes glitch. Try switching to a computer.
- Use browsers like Chrome or Firefox on a laptop for better access.
4. Use Off-Peak Hours
- Try accessing the portal between:
- 5:00 AM – 7:30 AM
- 10:00 PM – Midnight
5. Re-Login and Check Form Access
- Go to https://unnportal.unn.edu.ng
- Enter your JAMB registration number and RRR.
- If your form is still locked, continue to the next section.
If You See “Submission Failed. Try Again.”
This issue is usually caused by:
- Uploading files in the wrong format (e.g., Word or PNG)
- Files that are too large (over 200KB or 500KB)
- File names with special characters (e.g., @, %, #)
Fix It This Way:
- Convert all documents to PDF or JPEG.
- Rename files simply: e.g., passport.jpg, olevel.pdf.
- Compress large files using ilovepdf.com or compressjpeg.com.
- Upload the corrected files and click submit once.
- Wait patiently; do not refresh the page repeatedly.
