I am completely new at this fiddler thing and I have no idea what it does. I just know that I can't connect to anything without having fiddler on otherwise it just keeps loading and says I cannot connect to the internet. I used it to find a value in a game and I am stuck using fiddler to just gain access to the internet. I uninstalled it and everything and it will not go back to the way it was. I want nothing to do with this program anymore I just want my pc back for everyday use without having to launch fiddler every time to connect to discord or steam or the internet etc. I have tried checking and unchecking "capture https CONNECTs" many times. I have reset all certification multiple times. I have also went in a deleted all the ones from fiddler and nothing changed. I also know if I don't use "act as system proxy on startup" I cannot access the internet. Thanks.

Hi Kyle,

I'm sorry to hear about your issue using Fiddler Classic. By default, when Fiddler captures traffic, it sets itself as system proxy on your machine. When you close Fiddler, the system proxy settings should be updated and should not point to Fiddler anymore. However, it seems the last part does not happen on your machine, which is why you do not have internet access when Fiddler is not working - the proxy setting point to Fiddler, but it is not running. 

In order to resolve this, you can close Fiddler and open your proxy operating system settings (just write down Proxy in your Start menu). At the bottom of the page find the switch for proxy configuration and turn it off. Now you should have internet access even when Fiddler is not working.

Hope this helps.
