403 Error User Guide

Overview

A 403 Forbidden error means the server received your request to access the platform but refuses to authorize it — typically because your account or network doesn’t have permission to access the requested resource.

Common causes include restricted access rules, incorrect permissions, or browser cache/cookie issues.

How to resolve (Sonio + Chrome)

1) Fully log out and sign back in

1. Log out of Sonio completely.
2. Close all open Chrome tabs.
3. Reopen Chrome and go back to Sonio.
4. Log back into Sonio.
5. If the 403 is unresolved, continue to step 2.

2) Clear Google Chrome cache and cookies

1. Log out of Sonio.
2. Click the three-dot menu (top-right of Chrome).
3. Select Delete browsing data.
4. Choose a Time range:
   • To clear everything, select All time.
5. Check:
   • Cookies and other site data
   • Cached images and files
6. Click Delete data.
7. Reopen Sonio and log in again

3) Escalate to local IT if you still have the error

If the issue persists, contact your local IT team — it may be related to a local firewall and/or network restriction.
