If you have been asked to generate a HAR file by Rublon Support, here’s how to do it.
A HAR file is a useful tool for troubleshooting issues that occur in a browser. It records the network activity and interactions between the browser and the web server. However, a HAR file may also contain sensitive information, such as cookies or authentication tokens, that could allow someone to impersonate your account. Therefore, you need to sanitize the HAR file before sending it to Rublon Support.

3. Make sure the red light is on at the left side of the menu. This means the network activity is being recorded.
4. Check the boxes for Preserve log and Disable cache. This will ensure that the browser keeps the data across different pages.

Sanitize the HAR file
