getting "Error Code: 0" for mediation Ad request.

[hanhe cai]

I tried to add mediation for one of my App. I created the mediation placement and I added only Admob network for testing purpose.

Then I set the mediation ID with setAdUnitId() in my code. But I got error with the Ads request, which returned "HTTP response code 400" and "Error Code: 0". I was requesting interstitial Ads and I'm using Google Play services SDK. Please help!

Hi there,

It sounds like you're just not getting fill.

Hi Amy,

I manage to load the Ad now. I did not change anything.

Seems like the mediation placement needed some time to "register" itself in the server after creation.
Thanks.
