How do I send a .har file to Support?

Open the Network tab

• Chrome: Ctrl + Shift + I (Windows) or Cmd + Option + I (Mac) to open DevTools, then click on "Network"
• Firefox: Ctrl + Shift + E (Windows) or Cmd + Option + E (Mac)
• Edge: Ctrl + Shift + I (Windows) or Cmd + Option + I (Mac), then click on "Network" (with the WiFi icon)
• Safari: Cmd + Option + I, then select "Network" (with the circle and two arrows icon)

Reproduce the problem

Do whatever you need to do to get the error you're writing into Support about (e.g., Failed to Fetch, an Explorer query running very slowly, etc.). If the error has already occurred by the time you opened the Network tab, you'll need to refresh the page. When you do this, you should see several HTTP requests populate the Network tab.

You want something that looks like this:

and not like this:

You don't need to see exactly what's in the first screenshot. The point is that you should see HTTP requests in the output and that you need to reproduce the problem after you've opened the Network tab.

Save a .har file

• Chrome

  • Select "Save all as HAR with content".

• Edge
  • Right-click anywhere in the Network request table.

Once your .har file is saved, send it to Support.
