If you are using chrome then:

  • Click the context menu in the browser toolbar to the right of the address bar.
  • Choose Settings.
  • Select/Search the "Security and Privacy" section.
  • Choose "Cookies and Other Site Data" Ensure that "Allow all cookies" is selected.

This happens to me quite often too. The suggestion Google gives is wrong. Clearing cookies and restarting the browser does not fix it. Sometimes rebooting does, but that's a huge disruption.

What I found to work pretty reliably is to end the preview (dropdown), then click the EDIT button to go to the editor. Come back to the setup page, then try Debug again. Debugger should work again.

Turn off Preview
