Why Is the STI Portal Not Working?
The STI portal is a government website used by a very large number of people at the same time. When thousands of candidates log in during the final days, the server slows down. Other issues come from the user side: old browsers, weak internet, wrong data in the profile, or duplicate accounts. When the STI portal not working issue appears, knowing the cause helps you pick the right fix instead of trying random things.
- Server load: peak traffic near deadlines makes pages slow or blank.
- Browser cache: your phone shows an old copy of the page.
- Data errors: a wrong date or marks value stops the form from saving.
- Account issues: duplicate CNIC registration or wrong email.
- File issues: images that are too large or in the wrong format.

STI Portal Not Working: 9 Common Errors and Fixes
1. sti.pesrp.edu.pk Not Opening
If sti.pesrp.edu.pk not opening is your issue, first check the spelling of the address. Then switch between mobile data and Wi-Fi. Many users report that the portal works smoothly early in the morning or late at night. Use Chrome in incognito mode to skip old cache files. Never use look-alike websites that claim to be “STI portal mirrors”. Only the official address is safe.
2. Verification Email or Code Not Received
Emails can take a few minutes on busy days. Check the Spam and Promotions folders. Make sure your email address is spelled correctly. Pressing Resend again and again can block further codes for a while, so wait between tries.
3. CNIC Already Registered
This message means an account with your CNIC already exists. Maybe you made it last year, or a computer shop made it for you. Do not create a new account with a different email. Reset the password of the old account instead. Our STI login password reset guide explains how.
4. Profile Not Saving
The profile builder has four tabs: Personal, Academics, Experience and Qualification. Save each tab before moving on. A common cause is a marks mistake, such as obtained marks higher than total marks, or a wrong date format. Fill every field marked with a star.
5. No Internships Showing
The portal shows only posts that match your degree, gender and domicile tehsil. Men are placed in boys schools and women in girls schools. If your tehsil in the profile does not match your CNIC, or your degree does not fit the level, you will see an empty list. Check our STI eligibility guide to confirm you qualify.
6. STI Apply Button Not Working
If the STI apply button not working problem appears, it usually means a profile tab is incomplete. Complete all tabs, refresh, and log in again. Data-saver modes and ad-blockers can also stop buttons from working, so turn them off for this site.
7. Picture or Document Upload Error
Upload JPG or PNG files under the size limit shown. Rename long file names to short ones like photo.jpg. If the file is large, compress it using a free online tool before uploading.
8. Wrong Data After Submitting
If editing is still open before the last date, correct it yourself. If editing is closed, write to your District Education Authority with proof such as a DMC or degree copy. Keep screenshots of both the wrong and the correct information.
9. Password Not Accepted
Check Caps Lock and extra spaces. Then use the Forgot Password option. Do not make a second account because duplicate CNIC accounts can cause rejection later.
Best Time and Device When the STI Portal Is Not Working
A laptop or desktop with Chrome gives the best result because the full layout shows all buttons clearly. Mobile works too, but some tables and Save buttons are easier to miss on a small screen. Try to finish your application at least three days before the closing date. In the 2026 round, the reported last date is 18 October 2026, so do not leave it to the final night.
STI Portal Not Working Checklist
Before you call or visit an office about the STI portal not working, run through this short checklist. In most cases, one of these points solves the STI portal error on its own:
- Is your internet working on other websites?
- Have you tried another browser or incognito mode?
- Have you cleared cache and cookies for the site?
- Are all four profile tabs saved with a green tick or saved message?
- Is your domicile tehsil the same as on your CNIC?
- Are your image files small and in JPG or PNG format?
- Are you logging in to the correct account, not an old one?
If you answered yes to all of these and the issue is still there, the problem is most likely on the server side. Wait a few hours and try again before taking further steps.
Stay Safe From Fake STI Portals and Agents
When the official site is slow, fake pages and social media “agents” become active. Some ask for a fee to “submit your form fast”. Others ask for your password or OTP. Never share your login details with anyone. The STI application is free, and only the official portal can accept it. A shop can help you type data, but you should keep your own email and password and change the password afterwards.
Also be careful with links shared on WhatsApp. Always type the address yourself. A fake page can look exactly like the real one but steal your personal data.
What to Do If Nothing Works
If your STI portal not working problem is still there after you have tried every fix and the STI portal problem continues, collect proof. Take screenshots showing the error with the date and time visible. Then contact your district office. Our STI helpline and complaint guide lists the right offices and gives a ready-made complaint letter. Once your application is in, you can track it with our STI application status guide.
Remember, the STI portal not working issue is usually temporary. Stay patient, avoid fake helpers who ask for money, and keep trying with the steps above. A calm approach saves time and protects your application.
For official announcements, always check the official STI portal and the School Education Department Punjab website. Guides on this site are for help and awareness; the department’s notifications are final.
