Why would a https page work successfully when running a fiddler capture but then when i close fiddler, the page no longer works?
I have the decrypt https traffic options selected 

How would i get that to stop so i can capture why page does not work under normal circumstances?

Hello John,

 

There are different reasons why a request will work through Fiddler proxy but will fail otherwise - from improper application implementation to Keep-Alive settings and certificate errors. Refer to this blog post for some of the reasons and a detailed explanation of why each of them is "fixing" your connection when Fiddler is on.
