How do I create a HAR file and Console logs from my browser for an AWS Support case?

Short description

AWS Support uses a HAR file from your browser to investigate or replicate networking issues that you documented in a technical support case.

Important: You must have a Developer, Business, or Enterprise Support plan to open a technical support case.

Warning: HAR files and Console logs can capture sensitive information, such as user names, passwords, and keys. Before you send a HAR file and Console logs to AWS Support, make sure that you remove any sensitive information.

Note: These instructions were last tested on Google Chrome version 116.0.5845.187, Microsoft Edge (Chromium) Version 116.0.1938.81, and Mozilla Firefox version 115.1.0. Because these browsers are third-party products, these instructions might not match the experience in the latest versions or in the version that you use. In another browser, such as Apple Safari for macOS, the process to generate network activity logs might be similar, but the steps are different.
