Problem: Specific Traffic is Missing

I see some traffic in the Web Sessions List, but some traffic (for example, from a specific program) seems to be missing.

Solution: Check for Traffic Filters

Check to see if any Traffic Filters are enabled.

  • Check in the status bar


  • Check the Process Filter in the toolbar.


  • Check the Filters tab.


  • If you've written or set any Fiddler Classic Rules check those too.

  • Click Help > Troubleshoot Filters.... When you do so, traffic that would otherwise be hidden is instead shown in a strikethrough font. The Comments column will show which of Fiddler's filters was responsible for attempting to hide the traffic.
