This article explains how to generate a HAR file. 

HAR files are used to gather data from users’ browser which can be used to troubleshoot network or resource issues with the OnePlan support staff. This information includes detailed timing information about the requests made between the browser and the server.

Providing HAR files to the support team can help expedite the troubleshooting process.
