Master Promissory Note won't submit on studentaid.gov - tried everything!

omg same thing happened with my daughters MPN last week!! so frustrating!!! we ended up having to use Microsoft Edge in private browsing mode + disable all extensions. worked instantly after that. no idea why but something about the site hates chrome

This is a known issue with the studentaid.gov site when completing MPNs. A few technical solutions to try: 1. Make sure JavaScript is enabled in your browser settings 2. Try using a computer rather than mobile/tablet (the site isn't optimized for mobile) 3. Check if any browser extensions are interfering (try incognito/private mode) 4. Verify your son's FSA ID login credentials are working properly 5. Try completing it during non-peak hours (early morning or late evening) If all else fails, you should contact Federal Student Aid directly. Their systems have been overwhelmed with the new FAFSA changes.

I had the EXACT same issue with my daughter's MPN last month. Turns out in our case, there was a TINY checkbox at the very bottom of the page about authorizing electronic signatures that wasn't checked. The frustrating part was there was NO ERROR MESSAGE to tell us what was wrong! Have you checked that all boxes are ticked? Sometimes they're easy to miss.

you might need to try a diffrent bowser. i used safari and it worked good. also make sure you have java updated

I spent 3 hours on this exact problem last week and was ready to throw my laptop out the window! After nothing else worked, I discovered Claimyr (claimyr.com) which got me connected to an actual Federal Student Aid agent in about 15 minutes instead of waiting forever on hold. The agent walked me through a weird workaround - you have to clear cookies specifically for studentaid.gov (not just all cookies), log out completely, then log back in with your FSA ID, and try again. They also have a good video explaining the process: https://youtu.be/TbC8dZQWYNQ that helped me understand the MPN issue better.

Have you confirmed that your son created his own FSA ID? A common issue is that parents sometimes create both FSA IDs (parent and student), but for the MPN to work correctly, the student needs to have created their own FSA ID and be the one logged in when completing the MPN. The system can detect when it's not actually the student completing their own MPN and will silently fail.

the fafsa site is GARBAGE this year!!!! i had to call them 9 TIMES to fix problems with my daughters application. kept getting stuck on different pages and the submit buttons not working is just ONE of the many issues! don't even get me started on the SAI calculation errors on her account!!!

There's actually a technical explanation for this issue. The studentaid.gov site uses specific JavaScript event handlers for the MPN submission that conflict with certain browser security settings. Here's a specific technical solution I've seen work for many students: 1. Temporarily disable any third-party security software (just while completing the MPN) 2. Make sure your browser is updated to the latest version 3. Enable all cookies specifically for studentaid.gov domain 4. Try using a wired internet connection instead of WiFi if possible (more stable) 5. Complete the MPN in one session without navigating away If those steps don't resolve it, you'll need to contact FSA directly - unfortunately, their wait times are extremely long due to all the FAFSA changes and system issues this year.

UPDATE: IT FINALLY WORKED! After trying all your suggestions, what ended up working was a combination of: 1. Using Edge in InPrivate mode 2. Disabling our security software 3. Clearing cookies specifically for studentaid.gov 4. Making sure ALL checkboxes were checked (there was indeed a tiny one we missed!) The MPN is officially submitted and we got a confirmation email. Thank you all SO MUCH for your help! This forum literally saved us after days of frustration.

Congratulations on getting it sorted out! This is such a helpful thread for other parents dealing with the same nightmare. I'm bookmarking this for future reference - my younger daughter will need to do her MPN next year and I'm dreading it already. The fact that there was a tiny checkbox you missed with NO error message is just terrible UX design. Thanks for updating us with the solution that worked!

As someone new to this whole financial aid process, I can't thank you enough for documenting this journey! My son will be starting college next year and I had no idea the MPN submission could be such a technical nightmare. The combination of solutions you found (Edge InPrivate mode + disabling security software + clearing specific cookies + checking ALL boxes) is incredibly valuable. I'm screenshotting this entire thread to keep as reference. It's ridiculous that studentaid.gov doesn't provide clear error messages when something goes wrong - how are parents supposed to troubleshoot blind like that? Really appreciate everyone who chimed in with solutions!
