i used these settings:

public static void StartupFiddlerCore()
        {
            // Build startup settings:
            var settings = new FiddlerCoreStartupSettingsBuilder()
                                //.CaptureLocalhostTraffic()
                                .MonitorAllConnections()
                                .CaptureFTP()
                                .DecryptSSL()
                                .RegisterAsSystemProxy()
                                .OptimizeThreadPool()
                                .Build();
            FiddlerApplication.Startup(settings);
            //FiddlerApplication.oProxy.Attach();

        }

 

when i use WinSCP and use the fiddlerCore's ftp proxy to connect ftp server, the fiddlerCore's ftp proxy did net capture the ftp traffic.

 

the picture is winscp's proxy setting.

Hello S Cheng,

Not familiar with the WinSCP tool, but based on the documentation, you should try to explicitly set the proxy to point to the Fiddler proxy (as the tool does not use automatic proxy detection). The documentation also claims that localhost FTP connections are not proxied, which might also cause a problem.
