403 Forbidden error when saving — "Something went wrong while loading this page"

Question

403 Forbidden error when saving — "Something went wrong while loading this page"

Bhuvesh Rohankar 0

Extension name: AlgoRhythm

Product ID: 1aa0fde7-c29a-4950-aaa8-219ec6672dc6

CRX ID (Extension ID): chggifmaplgmobchnnpcfmcifpehdcfn

Store ID: 0RDCK9LD95N3

Issue description:

When attempting to save the Privacy tab for my extension submission, the page displays a generic error banner: "Something went wrong while loading this page. Please refresh to try again." This occurs consistently, even after refreshing, logging out/in, and trying an incognito window.

Technical details (from browser console):

The page makes a PUT request that returns 403 Forbidden:


PUT https://partner.microsoft.com/dashboard/microsoftedge/api/1aa0fde7-c29a-4950-aaa8-219ec6672dc6

Status: 403 (Forbidden)

This occurs twice in the console log, suggesting a retry attempt that also fails. All other fields on the page (Single purpose description, permission justification, etc.) appear filled in correctly, so this does not seem to be a validation issue but rather a backend permissions/authorization problem.

Steps to reproduce:

Navigate to Extension overview → Privacy tab for AlgoRhythm
Fill in required fields (or even without changes)
Click "Save & Continue"
Red error banner appears; PUT request to the dashboard API returns 403

Steps already tried:

Hard refresh (Ctrl+Shift+R)
Logging out and back in
Testing in an incognito window
Clearing cookies for partner.microsoft.com

Timestamp of issue: 04/07/2026 17:30

Request: Could you please check server-side logs for this Product ID around the timestamp above to identify why the PUT request is being rejected with 403? This is blocking me from completing and publishing my submission.

Hi @Bhuvesh Rohankar

Thanks for reaching out.

This is a known server-side authorization issue on the Partner Center backend. Since you've already tried clearing cookies, testing in InPrivate/Incognito, and re-logging, I can rule out standard browser or local state issues. The 403 Forbidden error on the PUT request means the backend API recognized your identity but refused to authorize the save action on your Product ID (1aa0fde7-c29a-4950-aaa8-219ec6672dc6).

To isolate and work around this, I suggest trying the following:

Verify if it's tenant-wide or endpoint-specific: Try saving changes in another tab (like Listings or Availability). If other tabs save fine, the issue is isolated strictly to the Privacy tab API route. If everything fails, it indicates an authorization synchronization lock on your developer tenant.
Test network/WAF blocking: Try performing the save over a different network connection (such as a mobile hotspot) to ensure your local IP or network is not getting flagged by Microsoft’s Web Application Firewall (WAF).
Bypass the UI via API: If you're in a rush, you can bypass the web portal completely and push your changes using the Microsoft Edge Add-ons API.

If none of these work, you will need to open a support ticket with Microsoft Partner Center Support so they can inspect their backend logs around the timestamp you provided:

Log in to the Partner Center Dashboard.
Go to Help + support (top-right) -> Contact Support and select Microsoft Edge Add-ons.
Before submitting, capture a network trace: Open DevTools (F12) -> Network tab -> check "Preserve log" -> click "Save & Continue" to reproduce the 403 -> right-click and export as a HAR file. Attach this HAR file to the ticket to expedite engineering review.

Hope this helps! If my explanation and the information I provided were helpful, I would greatly appreciate it if you could follow the instructions here so others with the same problem can benefit as well.
