[BUG]: DevProxy interferes with other apps which urls aren't watched #1268

Description

Currently when I enable DevProxy (as I need it for development) - some other apps, like the New Outlook and Whatsapp Desktop Client - stop functioning, like they don't seem to have internet access anymore until I stop the DevProxy and sometimes have to restart the app first, especially Whatsapp.

Expected behaviour

No interference with other apps which URLs aren't watched

Actual behaviour

Interference with other apps which URLs aren't watched

Steps to reproduce

Below happens instantly after starting the proxy, but sometimes after a little while - it's flakey buy always happens eventually

Outlook (using an Microsoft Exchange Online account, don't know if this is important)

1. Open Outlook
2. Start DevProxy
3. Send yourself an email from your phone - or even from Outlook (won't send)
4. It never shows up in Outlook as it lost internet access - same goes for trying to open an email which you haven't opened yet, or when trying to search

Whatsapp

1. Open Whatsapp
2. Start DevProxy
3. Try to send or download a file - messages seem to go through but not always
