I was trying to watch all the Google Analytics HTTPS traffic from an Android App but it's impossible. 

All the recommended settings on http://docs.telerik.com/fiddler/Configure-Fiddler/Tasks/ConfigureForAndroid were done. 

The smartphone barely connect to the network even though the settings are ok and well configured.

Hello,

I am using Fiddler in my home lab to see what encrypted traffic do my programs/apps send over internet. Fiddler is running under windows 10 on a dedicated machine. I have 2 client machines that use Fiddler as a remote proxy, one desktop with Windows 10 and one wireless smartphone with Android 7.1.1. Except for a few programs/apps (e.g. Viber, Skype), everything works fine. One of the main problems is that Android thinks it is offline. I could browse internet but PlayStore seems to be unable to download apps. So I decided to add some google hostnames to the proxy bypass list to see if this solves the problem. It seems that this list has no effect when Fiddler is running as a remote proxy.

Question 1: Is this how it is supposed to work or am I doing something wrong?

Another problem is memory usage: on the dedicated Fiddler machine I have upgraded from 6 to 8 GB RAM. It seems Fiddler uses nearly all RAM although I have limited the number of sessions to the minimal available (10000).

Question 2: Can I somehow tell Fiddler (using a script) to use e.g. only 6 GB?

 

I am using the latest Fiddler version.

Hi, 

I got 2 problems regarding Fiddler on mobile : 

The first one is the certificate. I made the configurations on my phone but I still can't download the certificate on this address:

http://ipv4.fiddler:8888/ (Device : Samsung S8)

Then, I changed my mobile with another one who already got the certificate, but here is the second issue: I cannot get my hits on Fiddler interface. All of them are secured with a lock "443". 

 

Many thanks in advance, 

Lydia.

When opening Fiddler, it kept hanging on the "Creating proxy..." step of the initial splash screen and wouldn't load. So, I tried to uninstall and reinstall it, and I keep getting an error (screenshot attached) during the install process (and, also during the uninstall process). It won't run at all now, I'm not sure if it's a Telerik issue or an issue with my computer (this isn't the first issue I've had in the past couple of days with my computer).

Unfortunately the new version 4.6.20172.31233 of Fiddler always installs to the users folder under C:\Users\alias\AppData\Local\Programs\Fiddler

What can I do to install the new version 4.6.20172.31233 silently to c:\program files again?

Thank you!

Hi all.

I use these settings AutoResponder (attach image).

REGEX:.+\.jpg$

http://mysite.com/123.jpg

But the problem is that these settings work for all users.

How can I make these settings  AutoResponder work only for a user with such browser settings?(attach image).

User-Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET)

Is it possible ?

Seems to happen primarily when I am trying to use eBay.com through Fiddler. I will get regular core dumps with the following stack trace (copied below this message). I am running on Ubuntu 14.04 with the full mono package installed. Am I missing a particular font that Fiddler needs on a particular dialog that it is trying to display?

Thanks much for even giving us Linux folks the option to use this great tool!
