Error Code 3, No fill

[Evgenii Fedorishchenko]

Hello!

I have two published apps. Those two apps have "ready" approval status in AdMob. The first app shows ads banners without any problems (both test ads banner an real one), but the second app doesn't show a test ads banner and I get the following error: 

AdMob onAdFailedToLoad, error:{
  "Code": 3,
  "Message": "No fill.",
  "Domain": "com.google.android.gms.ads",
  "Cause": "null",
  "Response Info": {
"Response ID": "null",
"Mediation Adapter Class Name": "",
"Adapter Responses": [],
"Response Extras": {}
  }
}

I have read tons of docs and howtos but after spending 2 days trying to find the reason I finally give up. I just don't know why my second app has problems with displaying test ads banner. I need some help.

Hi,

Error code 3, no fill error means that the ad request was successful, but no ad was returned due to lack of ad inventory. Kindly note that the SDK just requests ads to the ad server and does not have any control on the ads it serves. For test ads, you can refer to Enabling test ads.

This is more of an Ad serving concern rather than anything specific to the code implementation of the Mobile Ads SDK. I would recommend that you refer to AdMob Error Codes & Logs for more details about the issue.

If the issue still persists, kindly provide the below information via the reply to author option for further investigation

• app ID
• ad unit ID
• Mobile Ads SDK Version

So that we will review your account and let you know why ads aren’t showing.

Hello! Is there any results from the investigation?  I get "Error Code 3, No fill" even with test unit id...

Hi,

I have tried running the Google sample projects and able to reproduce the issue, upon checking the account we have found policy issue in your account. Kindly login to your AdMob account and fix the issue to enabling the ad serving.

Break down your traffic reports into meaningful segments using app filters such as app name, ad unit and country. This will help you gauge how changes to traffic sources or implementation can affect your ad traffic. You can use Google Analytics to get detailed information about your app visitors, and be on the lookout for any suspicious user behavior. Some questions to ask yourself:

• Where do my users come from?
• How are they interacting with my app?
• Which screens do they view in my app?

Learn more about how you can use Google Analytics in AdMob and how to implement the Google Analytics SDK for Android and iOS.

Kindly refer Understand your ad traffic and app users and I would recommend reaching out to the Product support team as they are better equipped to address your concern.

Hi,

Kindly ignore the previous mail.

We are able to load the ads in our Google sample project in a real device kindly check and revert back to us if the issue still exists. Make sure that you have solved the policy centre issues as they might impact the ad serving.

[Evgenii Fedorishchenko]

Thank you for your reply. The problem still exists. Moreover I don't see any issues in the policy center...

Hi,

Thank you for contacting the Mobile Ads SDK Support team.

I ran the Google Sample Project with the app ID and ad unit ID you have provided and was able to load the ads successfully. Could you try once by enabling the Ad Inspector ? and then share the export request and response file generated from the Ad Inspector for further investigation.

Note:You can export the ad response only after you add your test device in the AdMob UI.

For detailed info refer to this AdInspector document. Kindly provide the requested details via Reply privately to author option.

Please check this Getting started with Ad Inspector video to troubleshoot the “no fill” errors.

Hi Evegenii,

I have tried your other ad units in ad inspector and none of them got a fill, see attached screenshot. Have you seen any traffic in reporting? If not then it's an account related issue which only the Product support team can answer.

Unfortunately, there is no option to contact the Product support team directly. The only thing I was able to do is I posted my message to Community using the provided link. But alas, a month has already passed by and none from the support team reacted to my message. I am totally disappointed. There is definitely an issue with my AdMob account or my package id  but the AdMob console says there are no issues. Please help me. I have already been fighting with this problem for more than a month without any success. I checked everything I could  million times and didn't find the cause of No fill error for my packageId...
