F12 IEChooser - Network collection agent failed to start

Question

Hello !

I am trying to use IEChooser (F12) to track requests for a website in IE mode. This does not work on my computer : I can select the tab, navigate/edit the DOM, but the network tab itself is not working, I get an error "the network collection agent failed to start"

I also have an error that appears in the event viewer with the following message "Échec du démarrage de la session « DiagHubEtwSession.user_paged » avec l’erreur suivante : 0xC000009A". If I translate to english : "failed to start DiagHubEtwSession session with the following error : 0xC000009A"

I tried the following things (according to google searches) :

• Using both 32 bit and 64 bit versions
• Run the tool as both admin and normal user
• Enable the diagnostic hub service
• sfc /scannow
• Probably some other things that I forgot to note

Can anyone help me ?
Thanks !

Hello,

Based on the information you provided, I suggest you try the following method to see if it can solve the problem that the network collection proxy cannot be started in the browser developer mode:

1. Open cmd as an administrator and run the following command.

sc config diagnosticshub.standardcollector.service start=demand

2. Close the browser and restart it

Hey guys,

Just encountered this after upgrading to Windows 11, the service above doesn't exist so command did not work?

Just letting you know.
