I'm trying to figure out the error that occurred in the MS Store after the OS version upgrade  v.1709 OS Build 16299.402 -> v.1803 OS Build 17134.1 2018.04.30.
As a result of this error, any applications from the Store stopped loading. 
Actually the Store itself works as an application.

I.e. the Store starts up like charm, shows my account, shows what applications there are new, what needs to be updated. But when I try to download any application, I receive the message "Pending", "Starting download", but after a few seconds it is reset, appears again and after three attempts "Error: See details", "Something Unexpected has happened. Code: 0x80070015", "Could not install We'll retry shortly." message is appears.

Store app itself offers to update itself from version 11803.1001.9.0 to 11807.1001.13.0, but when I click on the "Update" button as described above - the "Starting download" message is appears, but after a few seconds it is reset, appears again and after three attempts,  "Error: See details ", "Something Unexpected has happened. Code: 0x80070015 " and " Could not install. We'll retry shortly." messages is appears.

In order to deal with this error, I decided to use Fiddler. I run Fiddler, then I run the built-in utility EnableLoopback and mark the checkboxes for all Store applications. When I start Store, I can see the exchange between the Store and the Microsoft servers in Fiddler window. But when I press the "Update" button in the Store window, there is not any activity that is described above, i.e.  "Starting download", "Error: See details ", "Something Unexpected has happened. Code: 0x80070015" and "Could not install. We'll retry shortly."  messages do not appear. But in the Fiddler window I can see that the request goes to the server https://watson.telemetry.microsoft.com/Telemetry.Request, but it does not respond.

If I discard Capture (in the lower left corner of the Fiddler window), then activity  appears in the Store window, i.e.  "Starting download", "Error: See details", "Something Unexpected has happened. Code: 0x80070015" and " Could not install. We'll retry shortly." messages appears again. But then in Fiddler there is no interception of traffic respectively (since I looked away from Capturing).

Is this behavior normal or is it some kind of mistake?
What am I doing wrong? And how do I see where the error occurs when Store try s download application from MS server?
I made a movie of the whole process through the screen recorder. https://youtu.be/d4kKjWH9WDo  If anyone wants to - he can view  so that it becomes more clear about what it is.

TIA

fiddler can't capture any network traffic. There is only one session captured that it's a update test session about fiddler itself.

 

my os is Win10 latest(1703),  can anybody help me?

I'm using Fiddler to capture HTTPS traffic for a mobile game (emulated on Nox version 6.2.3.1). After you click past the title screen, the game takes you a loading screen, which downloads data from the internet. It always stops working once Fiddler captures the base URL for the game. An example of that error is shown in the first image. It seems to be working fine without Fiddler running.

It doesn't just effect Nox and the game, it also effects my web browser (Google Chrome). It always states that my "connection is not private" and prevents me from entering most websites with Fiddler on (some exceptions include this website and Discord), shown in the second image. When I exit out of Fiddler, it works perfectly fine again.

I believe that the reason why Fiddler is acting this way is because I have "Decrypt HTTPS traffic" turned on. For Nox, I followed the instructions shown here to capture the HTTPS traffic for that game (including downloading the certificate). I need to have "Decrypt HTTPS traffic" turned on, otherwise it won't capture all the HTTPS traffic for the game. However, when that option is turned off, the game works fine, so is my web browser.

Is there anyway around this? I'd like to be able to capture HTTPS traffic normally without getting all these errors. Any help would be much appreciated.

Hi

I don't know what's wrong, when I apply a filter with wildcards it doesn't include any https requests, only those that go through http. What am I doing wrong?

Fiddler is not displaying the traffic though page gets loaded fine on chrome. What could cause this issue as there are no filters.

I keep getting the error "HTTP Request specified an invalid port number" in Fiddler.

It looks like the problem is that Fiddler is appending a "1" to the front of my port number.

The address I am plugging into my web browser is http://ourlocalserver:14485/api/...

This works fine when Fiddler is not capturing traffic. As soon as I turn Fiddler on, it starts failing, and Fiddler logs the address as http://ourlocalserver:114485/api/...

Notice that the port is now 114485 instead of 14485.

How can I get Fiddler to stop modifying the port number so that my tests work correctly?

Very new to this technology, apologies if this is a basic question. I am trying to understand if I download Fiddler on my mobile phone (iPhone 6), if I can "sniff" wifi packets from laptops/other devices on the same wifi? 

I'm learning Fiddler .
I use Fiddler certificate inside browser web, but Can I install Fiddler Certificate inside every application for Windows ?
Help me !

I can monitor almost every packet that passes through my device, but only the ones from Apple such as "http://api.smoot.apple.com:443" "http://keyvalueservice.icloud.com:443" "http://api-glb-msp.smoot.apple.com:443" are all encrypted.

 

I followed all instruction and guides, trying to solve this problem.

Is the device required to be jailbroken to decrypt Apple traffics? Or is there a way to solve this?

Hi,

I am software engineer.
Regarding license, would you mind letting me know whether it is ok for me to use Fiddler for work or not?
I do not embed the fiddler to product.
I will only use to analyze web packet.

Thank you in advance.
