I have a .net app (using framework 4.7.1) making a simple call to fetch images from various sites. One site for some reason will always timeout the request. But if I use Fiddler as a proxy, then it always works just fine. The image URL also works just fine in a browser. I'm aware of the various things to look for when Fiddler seems to 'fix' your app, but none of them seem to apply here. I have tried using different protocols in options ... https ... protocols to see if I could get Fiddler to also fail in the same way, but no luck, it always succeeds. Even if I uncheck 'capture https connects' it works.
Any ideas what Fiddler could be doing to make it work so I can fix my app?

Hi James,
Hard to say what exactly might be causing the timeout in your .NET application but you could try some of the suggestions provided in the following resources:
