If you are using MobyMax and encounter a "403 Error", this usually means that your school or district firewall is blocking access to the platform.

This error is commonly seen in schools using Securly. A 403 error is an HTTP response code that indicates the server understands the request but refuses to authorize it—typically due to web filtering settings.

How to Fix It

To resolve this issue, your school's IT professional will need to whitelist MobyMax in the Securly filter settings.


Steps to whitelist MobyMax on Securly:

  1. Visit the Securly admin dashboard.

  2. Add the following domains to the approved list:

    • www.mobymax.com
    • http://assessments.mobymax.com/
  3. Save changes and refresh your browser.


Once these domains are whitelisted, access to MobyMax should be restored.
