Hi All,
I am trying to record an application using fiddler 2, during recording its not even loading login page.
When checked in Fiddler logs and Inspector we see below message
"
fiddler.network.https> HTTPS handshake to "Application" (for #2) failed. System.IO.IOException Received an unexpected EOF or 0 bytes from the transport stream.
"
This is happening when "Decrypt HTTPS traffic" is checked, when unchecked, application is working fine.
We tried by enabling/disabling other security options(SSL 3.0, TLS 1.0, 1.1, 1.2) but failed.

Please note, we are able to record the same application using fiddler 4 but as per recommendations we have to use fiddler 2.

Please help.

Thanks in Advance,

Is there a .dmg download for fiddler on Mac? I can only see an .exe on the site.

 

Thanks. 

Hi - running Fiddler Web Debugger (v4.6.2.0) on W7 64

1) Running a java app (q.jar, attached)

2) I set proxy in Java control panel:

Control Panel>Java>General>Network Settings:
Use Proxy Server:
Address: 127.0.0.1 (or localhost)
Port: 8888

3) I launch q.jar (double-click in Windows Explorer) which gives me a java warning message that the app cannot connect to the web server.  This is normal (the web server was taken down a few years ago), so I am trying to use fiddler to redirect to my local server.

But I cannot get fiddler to capture the q.app traffic to get the needed config info for redirection.

Could anyone please help me?

Thanks -

Sam

upgraded fiddler on administrative signon.  made changes for port.  ie and chrome no longer work on admin signon but work okay on user.

 13:59:48:0873 Assembly 'C:\Program Files (x86)\Fiddler2\CertMaker.dll' was not found. Using default Certificate Generator.
13:59:48:1273 /Fiddler.CertMaker> Using Fiddler.DefaultCertificateProvider+CertEnrollEngine for certificate generation; UseWildcards=True.

 

hi sometimes i connect local fiddler to another fiddler that is on my server

i intend use fiddler and filtering while bypassing my network's filters

 but sometimes i receive this error

"The client failed to send a complete request on this REUSED connection before the timeout period elapsed; 0 bytes were read from client."

but its not always

Hello,
I am using Fiddler to monitor HTTPS traffic for our private project. After upgrading to Windows 10 and installing Fiddler, I am unable to create a root certificate. I tried using Both CertEnroll and MakeCert and both returned that they cannot create a root certificate:

makecert.exe returned -1.

Results from C:\Program Files (x86)\Fiddler2\MakeCert.exe -r -ss my -n "CN=DO_NOT_TRUST_FiddlerRoot, O=DO_NOT_TRUST, OU=Created by http://www.fiddler2.com" -sky signature -eku 1.3.6.1.5.5.7.3.1 -h 1 -cy authority -a sha256 -m 132 -b 01/07/2015

Error: Can't create the key of the subject ('JoeSoft')
Failed

Every time when changing the service I Reset All Certificates and/or Removed Interception Certificates. Also the key in AppData/Roaming/Microsoft/Crypt/RSA/{LONG_ID} is nowhere to be found (the folder is always empty).
After browsing through forums, I followed some instructions and downloaded the Bouncy Castle Certificate Maker (the one suggested for Android) and that one created 2 root certificates and added them to Windows so they will be trusted. After doing so, all my HTTPS traffic looked like HTTP with tunneling. When looking into that issue, I found that in Text view it said 

"This is a CONNECT tunnel, through which encrypted HTTPS traffic flows.
Fiddler's HTTPS Decryption feature is enabled, but this specific tunnel was configured not to be decrypted. Settings can be found inside Tools > Fiddler Options > HTTPS."

AND the logger returned a few of the following:

"10:02:38:5419 !Certificate cache didn't find certificate for [server.com]. Returning null to thread #30. ___ 10:02:38:5419 fiddler.https> Failed to obtain certificate for server.com due to Certificate Maker returned null when asked for a certificate for server.com"

AND

"Failed to create certificate for server.com: The requested operation cannot be completed. The computer must be trusted for delegation and the current user account must be configured to allow delegation."

In the properties of a tunneling connection, I found

"X-HTTPS-DECRYPTION-ERROR: Could not find or generate interception certificate."

 

Do you have any solutions for me? I'd really appreciate it. Thank you! :)
