Question

I’m developing an app on WP7 and decided to add a Microsoft Advertisement to my application.

I added the control and setup the width/height, inserted my app id and ad unit id and published it to my phone. However I keep getting the following error:

An unexpected error occurred during response processing (Name: ECN)

I don’t receive this error when use I “test_client” for app id and “Image300_50” for ad unit id.

Does anyone have any clues as to what the reason for this error may be?

Answer 1

I found this official statement from Microsoft about that error, and it appears to be that there aren’t any ads to match your app.

This error is only visible to app developers that are debugging the
use of the Microsoft Ad Control in a development environment. As of
February 24, 2011, this scenario will now return the error “No ad
available”. In production the ad control would simply not display an
ad if there is an error or if there is no ad to display. There is no
user facing impact. Please reference the Monetization Best Practices
document (attached) to review the best practices you can incorporate
to ensure you are maximizing the possibility of Advertisers desiring
to reach your application audience.

I also found that when I was getting the error, I was using the wrong width and height for the control, and fixing that got the ads to appear.
