Im trying to decrypt the traffic from an application that used to work in the past months without any issue, however today when i tried to view the traffic i just saw this error in fiddler:

 

fiddler.network.https> HTTPS handshake to 104.28.25.251 (for #73) failed. System.Security.Authentication.AuthenticationException A call to SSPI failed, see inner exception. < The message received was unexpected or badly formatted

Win32 (SChannel) Native Error Code: 0x80090326

 

Im not sure what im supposed to do here, seems like there is an issue with the Protocols that its using?

Hi All, 

I'm using Fiddler 5.0.2.   And filter rules were set to make Fiddler show only specific Hosts session.  However, the rules does not work for error code session. All error code sessions, no matter what its host is, will be displyed in session window. Such as 404 code and 504 code. How can I solve it?

Any help is highly appreciated.Thanks in advance.

 

Hello,

 

Version 5.0.20202.18177 fails to completely uninstall leaving an entry in the control panel, that when clicked pops up a dialog window stating there is no app associated with it.  How do I remove the entry for this version of the program. I have tried re-installing and un-installing the current version.

 

thank you,

stephen

I have switched on "Require Proxy Authentication", as I understand it this would accept a default username:password combination of 1:1.  In my application if I configure the httpclient proxy settings in my application with 1:1 it lets me through, if I configure it with 1:2 it doesn't, so all as expected there, but if I send 1:1Iamabadpassword then it appears to let me through. 

In the auth inspector I can see that the decoded user/pass combination is the same as I pass from the client application.

Am I missing something?

Thanks

Mark

I am trying to look at the traffic using the latest version of Fiddler Everywhere (I can't figure out how to find the version number), but no traffic is being captured.  The switch on the tab is slid to the right and it says, "(Capturing)", but nothing is being displayed.  I've tried multiple times and tried closing and reopening my browser, Chrome, but nothing is being shown.  Any ideas on what is wrong?

How do I get rid of the FIddler Everywhere HTTPS cert? Seem to cauase a lot of problems in Windows after being installed.

Log info:

14:12:13:8724 !Fiddler.CertMaker> Unable to auto-trust root: System.Security.Cryptography.CryptographicException: 访问控制列表(ACL)结构无效。

 Seek help sincerely.

 

Hi,

I have some redirection code in my test automation that does not work when FiddlerCore 2.3.8.5 is referenced.

When I update to 4.6.2 (through Install-Package into my .csproj) the redirection starts to work.

Questions

1) Did something change between 2.3.8.5 to 4.6.2 to affect WS traffic to localhost?

2) Is there a better way to code this and make it work with 2.3.8.5?

 

 

 

I have a question in stackoverflow, fyi..

https://stackoverflow.com/questions/63073681/how-to-redirect-https-tunnel-traffic-to-https-localhost8444-with-fiddlercore

 

Basically, my need is:

 

Redirect https tunnel traffic to https://localhost:8444 from my prod endpoint.The CONNECT has an upgrade to WebSocket and the HTTPS traffic is through WS messages.

My automation code:

        /// <summary>
        /// Thread function to start fiddlercore and initialize event handlers
        /// </summary>        
        private static void FiddlerMocking()
        {
            try
            {
                // Set up FiddlerCore and its handlers
                // Hook up our callbacks
                Fiddler.FiddlerApplication.BeforeRequest += delegate (Session session)
                {
                    Console.WriteLine("BEGIN-" + session.fullUrl);
                    
                    if (session.fullUrl.Contains("XXX-int.YYY.com"))
                    {
                        if (session.HTTPMethodIs("CONNECT"))
                        {
                            log.Comment("CONNECT---" + session.host.ToString());
                            session.oFlags["x-replywithtunnel"] = "GenerateTunnel";
                            return;
                        }
                        else if (session.HTTPMethodIs("GET"))
                        {
                            log.Comment("GETBEFORE---" + session.host.ToString());
                            session.host = "127.0.0.1:8444";
                            log.Comment("GETAFTER---" + session.host.ToString());
                        }
                    }
                    else
                    {
                        Console.WriteLine("IGNORING-" + session.fullUrl);
                        // following will not work in 2.3.8.5 but will work in 4.6.2
                        //session.Ignore(); 
                    }

                };
                
                Fiddler.FiddlerApplication.OnValidateServerCertificate +=

                                    new   System.EventHandler<ValidateServerCertificateEventArgs>(CheckCert);
                Fiddler.CONFIG.IgnoreServerCertErrors = true;

                // This is to bypass traffic related to iframe
                Fiddler.CONFIG.sHostsThatBypassFiddler = "https://*.resources.office.net";

                var rand = new Random();

                Fiddler.FiddlerApplication.Startup(rand.Next(9100, 9900),
                    FiddlerCoreStartupFlags.DecryptSSL |
                    FiddlerCoreStartupFlags.MonitorAllConnections |
                    FiddlerCoreStartupFlags.RegisterAsSystemProxy |
                    FiddlerCoreStartupFlags.CaptureLocalhostTraffic);

                // Enable HTTPS capture and add session handlers
                FiddlerTaskLibrary.EnableHttpsCapture();
                
            }
            catch
            {
                throw;
            }
        }

 

Please help.

Thanks,

Amrendra
