First of all I'll say that I've investigated it deeply. I used to have fiddler 4 , earlier versions and never updated. When my computer turned to sleep , I was able to wake it by trying to rdp it. The connection itself to rdp - woke the computer ( via network card) and the computer awoke ,and then I could connect to it. this feature is called "wake on link". After installing fiddler ( latest version) , suddenly my computer won't wake up from sleep when trying to connect to pc. at first I didn't know what whet wrong and then I started uninstalling latest installed programs When I uninstalled fiddler , it started waking the computer So I don't know what's you've done in the last version , but it f*s some other functionalities. please fix it.
