Generate a HAR file to correct errors

Our support team may need additional information about the network requests generated by your browser. In this case, we may ask you to export the network requests that were recorded during the problem and send them to us as a HAR file.

Important note: A HAR file may contain sensitive data such as cookies and websites visited. Anyone who has access to the HAR file could view this data. Make sure to handle HAR files securely. Cloudflare provides a HAR sanitizer that you can use to remove sensitive data.

Steps for creating a HAR file in different browsers

• Google Chrome
• Microsoft Edge
• Safari
• Mozilla Firefox 

Google Chrome

1. Open Chrome and navigate to the page where the error occurs.

2. Click on the ⋮ button > Go to “More tools” > “Developer tools”.

3. Click on the “Network” tab and leave it open.
4. Make sure that the recording button is red (if it is gray, click on it to activate it).
5. Make sure that the Retain log checkbox is activated.

   

6. Click on the button with the diagonally crossed-out gray circle to delete any existing logs in the “Network” tab.
7. Reproduce the problem. For example, if your problem is that you cannot log in, try logging in again. 
8. Click on “Export HAR” to download the file.
9. Rename the file and remove the .com (as files with the .com extension are often classified as suspicious by spam filters).
