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.
