Generate and Analyze HAR Files
A HAR (HTTP Archive) file shows the sequence of redirects that happen during a login transaction. It's an excellent tool for debugging authentication issues, as it can identify where things get stuck. A HAR file is a JSON formatted log of a web browser's interactions with a web server. If authentication isn't working as expected, you can generate and analyze HAR files to find issues. Including a HAR file in your support requests can help speed up the troubleshooting process.
