Android 7.0 

Using Fiddler as a proxy to decrypt https traffic from a browser on the phone works ok. However, when using some apps I get:
Trust anchor for certification path not found

Is there a way around this?

 

before i use fiddler, there is no certificate in my pc,

when i use fiddler to decrypt https traffic,operate like picture 1.png,,there are three certificates in my pc,picture 2-1,2-2,2-3

 

how to remove certificates from pc?

i operate like picture 3-1.png，，，but still have one certificate in my pc,picture 3-2.png  why?

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.
