I'm using Android Studio's AVD to run Chrome for Android.

I've installed the fiddler CA by going to http://<pc-ip>:<fiddler-port>, downloading the FiddlerRoot certificate, and Trusting that certificate through settings on the virtual device.

I've set up the device to proxy through Fiddler.

I can successfully load the Fiddler Echo Service, and http://example.com/.  Presumably all http-only traffic works, but it's hard to find examples online to test.

An example request to Google is 

 

 

The response is 

 

No other traffic flows on the session, and it eventually times out with the 🚫 icon.

The Android device is continually polling to establish these connections.  When I disconnect the device from the proxy, Fiddler annotates the request:

 

Fiddler prints a log message for each of these requests

I don't think this is an issue.  I understand it to mean that Chrome for Android doesn't supply a Host header, and as the pastes above show, Fiddler automatically inserts an appropriate one.

The symptom in Chrome for Android, then, is that when I try to access an https site, the browser hangs until it gives ERR_CONNECTION_REFUSED

I'm at a loss here.

 

 

Hi!

We have this error when trying to write a temporary .har with Fiddler. We write a temporary file with Java using the ExeAction.exe with the name "out.har", rename it and then upload via FTP. However, sometimes we have a problem with the file being already used.

The error detail is attached.

We write the out.har using Java and Fiddler using the ExecAction.exe.

If you need anything else just say it, we've been struggling with this error for a while.

Thanks!

 

I had issues with registering an account. So I followed the directions and emailed sales. No response after 72 hours. Then I tried feedback. No response either after 72 hours. What kind of half asses operation are you all running when you don't even bother to reply to email inquiries? Dunno. Someone sucks at their job and they need to be fired.

I tried a lot of solutions,none of them work. I  tried to install the trust root form the store didn't work. Fiddler also blocks internet connection when I enable the HTTS decrypting. Please help. 

Hi,

I installed Fiddler on a windows pc, and I started it, then I want to use a web browser to view fiddler session, does it support to view or control fiddler remotely?

Hello. I am currently looking to hook up a application that is not inside of the AppContainer list. How would one do this? I have attached a screenshot of the AppContrainer Loopback Exemption Utility. 

Hello! I have been using fiddler and i noticed that after a few minutes or maybe hours my wifi modem just crashes or loses connection!

I am on a laptop using wifi!

And every time it crashes and all of my devices lose connection and i have to wait 5 or 10 minutes for it to get back on running!

 

Please help!

Hello,

I have a JSON string and I want to parse it to an object (to do some query after that).
I have found Fiddler.WebFormats.JSON.JsonDecode() but the returned JSONObject has no method to get or set content.

How to decode and use JSON strings ?

Thanks for any help !
