Test Rewarded ad not displaying - Ad failed to load: LoadAdError(code: 3, domain: com.google.android.gms.ads, message: No ad config.)

Question

I'm currently unable to display a test rewarded ad. I am using the rewarded ad Sample ad unit ID provided in the doc: ca-app-pub-3940256099942544/5224354917.

I am getting error code 3, which according to the documentation:

The ad request was successful, but no ad was returned due to lack of ad inventory.

Which doesn't seem to make sense as this is a test ad, and should always be available?

The full error:

Ad failed to load: LoadAdError(code: 3, domain: com.google.android.gms.ads, message: No ad config.) => No ad config.

For reference, I've also opened an issue on the googleads-mobile-flutter repo with the full log outputs.

Any ideas why I wouldn't be able to fetch even a test ad?

Also please leave a comment if you've been able to successfully display test rewarded ads or real rewarded ads with this plugin lately.

Answer 1

I was using the same ad Unit to test two days ago and it was working but not working today with the same error you are having.both the Android Ad unit and the IOS ad Unit so i believe the issue is from the Network.

Answer 2

I have had this exact problem for a week. Finally today I switched it to the real ad id and it worked. It looked like a real ad but at the top it was labeled "Test Ad". Do you think that means I can use it until they fix the real test add or are they going to yell at me?
