How to save a HAR File

Sometimes when a ticket is raised due to sign-in issues, content issues, or other network-related issues, the Support team will ask you to supply a HAR file. This file is extremely useful for diagnosing these sorts of issues, as it contains information that shows network errors alongside other network information that can help us identify the root cause of these issues.

This guide is to show you how to get a HAR file and send it across to us. When recording and saving a HAR file, please start from the point before you begin to encounter the issue. If the issue is that Content won't send back the right information, begin the process from the My Learning page. If it's an error that occurs on Sign-In, start at the login page.
