I successfully saved the request and created a session which I want to reply later using fiddler core and C# code.
This worked great for some time and than it just stopped probably when nginx was added and turned on the geo IP location.
I did testing with Fiddler 4 UI app and got very strange results when run reply from various PC machines. On most machine it fails with below raw response with error message is:
HTTP/1.1 502 Fiddler - Connection Failed

System.Security.Authentication.AuthenticationException A call to SSPI failed, see inner exception. < The function requested is not supported
Win32 (SChannel) Native Error Code: 0x80090302
I have tried Fiddler 4 on AWS machine in cloud and from that one it is still working using system proxy but on test machine when we run testing it is still failing and tried couple more machines same.
I tried than to use Gateway Override and use Manual Proxy Configuration to avoid if there is some IP blocking. I used squied
Please find attached .saz archive of the saved request which I want to reply (remove .jpg extension by renaming the file and file type should be .saz).

Hello Milan,
I'm using very old FiddlerCore.dll for .NET 2.0 v2.4.5.6. Does that version of FiddlerCore supports new TLS1.2 protocol?
This version does not support TLS1.2. FiddlerCore uses the SSL/TLS protocol implementation of the .NET TLS1.2 is supported since .NET Framework 4.5
You could try the newest version of FiddlerCore. It is build against .NET Framework 4.0, 4.5 and .NET Standard 2.0
