  • Open Google Chrome.

  • Press Ctrl+Shift+I (Windows/Linux) or Cmd+Option+I (Mac) to open Chrome Developer Tools.

  • Make sure that the Preserve log option is enabled in the Network tab.

  • To start recording, click the round, gray recording button in the Network tab. If this button is gray, no recording is taking place. If the button is red, a recording is currently being created.

 

  • First, clear all previous activity by clicking the Clear button.

 

  • Reload the page where the problem occurred, then reproduce the problem.

  • To save the recorded data, right-click on the grid and select Save all as HAR with content.
