We do have a WPF application that send http request and web service calls to a server. We are also using TLS 1.2.
Everything is working find except when we run over a VPN connection. At one point, our web service call seems to be get stuck and the client do not get any response back from the server (and no timeout).
The VPN client software that is currently in used by the customer is Cisco AnyConnect version 3.x version.
Now when I run Fiddler 2, to investigate the issue , everything is working fine !
Why Fiddler would avoid our web service call to be stuck ? Is there a way I can run Fiddler in a mode that I could debug our problem ?
Any suggestion would be appreciated ...
