Screenshot of error

When adding components into a project the download fails with the following:
“Error downloading component: MD5 hashes don't match”

Screenshot attached

Components Reported to be effected:

IDEs Tested:

Steps to reproduce:
-Create Blank Xamarin Android Project in Visual Studio 2015 (see version info following description. 
-Right-click Components -> Get More Components
-Search and find effected component
-Add To App
-In Solution Explorer, under components, Right Click XM.CropImage (Error)-> Edit Components ...
-Underneath the logo showing XM.CropImage, I see a Red error message stating:
Error downloading component: MD5 hashes don't match
-There's a link to retry. The error message shows again,.

Additional Testing:
-An engineer opened the .info that came with the Component (Tested XM.CropImage) after using solution explorer to add the component. 
-The .info has a Hash property in the json and shows the value: "Hash":"e9757ae3801b251ef6396b4a9ee7e4ac"
-Downloaded XM.CropImage from https://components.xamarin.com/download/xm.cropimage

What I have found is that the IDE is calling the following to download the component.  


That is returning a zero byte file.  Will need to pick this back up next week.

We have deployed a workaround for this defect.  You should not see the error.

I have been asked to leave the bug open for now while the web team investigates a better fix.
Comment 3 David Greene 2017-08-07 21:39:42 UTC
I've verified the components listed above, and others noted are now downloading as expected.
Thank you!
