How to Generate a HAR File

When investigating technical issues, we may ask you to provide a HAR (HTTP Archive) file. A HAR file records network requests made by your browser while loading a webpage.

We usually request a HAR file when we can’t reproduce the issue on our side or need more details about what happens in your browser. It helps us analyze requests, responses, loading times, and other technical details to identify the cause of the issue.
