VMware.exe + Proxifier = Hangs or Freezes (responsible for the internet connection is but vmnat.exe/service)

if i remove the vmware rule in proxifier there is no Hangs or Freezes from vmware but too no proxy.

There is no problem with the network setup from vmware.

previously i used proxycap+Fiddler and its works with the vmnat.exe/service)
but there is a winsock conflict between proxifier and proxycap now i removed
proxycap.

 

 

Fiddler only working on http request from my android mobile apps. Fiddler is best more then others software but main problem is that, i can't capture from facebook app. Also play store, instagram and youtube are not capturing. Already i tried using 6-7 android phone, but i was can't capturing.

Admin please try on fiddler using your android phone facebook app. Then you will understand and can solve it.

I am using Lava Iris, Version 7.0, also i tried using lower version on different mobile (but not working).

 

I am waiting for admin reply and solution. Advance Thanks.

I have installed Fiddler, and made changes in Tools - Fiddler Options - HTTPs - checked "Capture HTTPs Connects" and "Decrypt HTTPs Traffic".

While running the Fiddler, I am not able to access / open any websites in any browser IE / Chrome. Below is the error I am getting.

Certificate Error: Navigation Blocked

There is a problem with this website’s security certificate.
The security certificate presented by this website is not secure.
Security certificate problems may indicate an attempt to fool you or intercept any data you send to the server.

If I close the Fiddler, I am able to open all the websites in IE / Chrome. Could you tell me how to resolve this issue.

Thanks

The beginning of the problem:

 

For months my computer would take about five minutes for HTTPS connections to function. As a result, Skype could not connect during this time and any HTTPS web requests would be stuck in "Establishing Secure Connection" during this time. I finally fixed the issue by removing all the DO_NOT_TRUST_FiddlerRoot certificates that I found in the "Personal" store.

 

Since then, fiddler is unable to decrypt HTTPS requests properly. Instead, Chrome displays a Privacy Error. I have seen other people on this forum with this problem fix the issue by upgrading Fiddler, checking a dll, or trusting the root certificate. On these points:

My Fiddler Web Debugger is v5.0.20182.28034 for .NET 4.6.1 (Running ELEVATED)
I do not understand what DLL I should be looking for in order to ensure that I have the right certificate authority. I have the CertEnroll engine.
In Tools > Options > HTTPS > Action:

• I have never noticed a change when I choose "Reset All Certificates".
• "Trust Root Certificate" does not work, the log shoes an error message: "The RFC server is unavailable"
• I am able to "Export Root Certificate to Desktop" and install these certificates in the "Personal" store, but not "Trusted Certificate authorities".

As far as I can see, the basic problem is a permissions issue:

• I can't delete a FiddlerRoot certificate (a certificate that I do not believe is the current root) from Trusted Certificate Authorities. (error: RFC server)
• I cannot install a new root into "Trusted Certificate authorities" (error: store is read only, or did not open properly)
  
  

Any ideas on what permissions specifically are neededfor these RFC server error messages to be fixed?

 

Appreciate your help.

windows 10 connected to the internet through wifi, no proxy. I need to read a curl request to rewrite in c# code.

using curl 7.61.0 and fiddler 5.

this command just works fine:

  curl -X POST -u "73b63264-b68c-4591-af76-96f325969d0b":"X7bECApaBi0o" -F "file=@c:\temp\1.json" https://gateway-fra.watsonplatform.net/discovery/api/v1/environments/e40e7c0d-25de-4ae5-a079-90877a745de0/collections/029a29d3-2ed1-4cf3-be81-b78e35d5ce0f/documents?version=2017-11-07

with fiddler running the command above works fine too ma no traced into fiddler.

this command is traced into fiddler but fails to execute:

curl --proxy http://127.0.0.1:8888 -X POST -u "73b63264-b68c-4591-af76-96f325969d0b":"X7bECApaBi0o" -F "file=@c:\temp\1.json" https://gateway-fra.watsonplatform.net/discovery/api/v1/environments/e40e7c0d-25de-4ae5-a079-90877a745de0/collections/029a29d3-2ed1-4cf3-be81-b78e35d5ce0f/documents?version=2017-11-07

this the error "curl failed to verify the legitimacy of the server and therefore could not
establish a secure connection to it. To learn more about this situation and
how to fix it, please visit the web page mentioned above"

 

Inspecting the requerst in fiddler , this the raw data of request, but i need to extract the body of request. How do i do?

Thanks.

Hi,

 I have been using Fiddler for a long and working fine but this morning I updated to latest version and things got weird. I am hitting API from Visual Studio C# code but fiddler has stopped capturing my request. On top of it , it has blocked my request as well, so I am not able to run my code in capturing request.

When I turn off the capture, it let my code execution complete but that way I am not able to see my request in fiddler.

 

I have also enabled the Decrypt HTTPS traffic but I did not get the option to save the Certificate "Trust the Fiddler Root certificate?"

 

Although if I am doing browsing through browser, it is capturing all the request but few request have the Lock icon against them.

 

Hello forum,

i would like to use Fiddler under Linux:-) Does the Windows-version and the Linux-version
currently offer the same features ?

Thank you!

Joe

An program I want to capture HTTPS traffic from uses Mozilla's pem file with SSL certificates that should be trusted, I want fiddler to mimic one of these certificates so I can go through the SSL pinning. I don't know how and if this is possible so if anyone can help I'd appreciate it!

Hi,

I'm trying to run fiddler while installing an application from Windows Store. It was working today but I don't know what happened.

The problem is, Fiddler shows yellow bar saying "The system proxy was changed..." When I click on it, it uses a proxy server for my LAN.

Using a proxy server for my LAN, disables windows store from running.

When I go to Internet Explorer > Options > Connections > Lan Settings > Uncheck Use a proxy server

Windows store will run, but Fiddler will show the yellow bar again and if I click on it, it will reenable using proxy server.

 

HELP PLEASE

Hello, dear Telerik team and pro customers!

I signed up at trial version of Kendo UI. And installed it.
But can't find out without your step-by-step help provided, how it could help to passthrough ASP.Net and Fiddler Web Debugger restrictions to upload files larger than 2GB?

Which one tool should I start, find there same options as Composer tool at Fiddler Web Debugger and try to upload content I need?

Thanks in advacne,
