Ad failed to load: 3

[Punyisa]

I have tested the ad code, and the ads load normally. However, after publishing the app on the Google Play Store, I encountered the following error:

 E  Ad failed to load: {
  "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 verified that the ad unit ID is correct, and the AdMob dashboard shows that it is ready. Additionally, my app's policy compliance has been approved for displaying ads.

Even after reverting the code for testing and adding the test device, I still encounter the error: "Ad failed to load: 3".

Please help me.

Hi,

Thank you for contacting the Mobile Ads SDK Support team.

As you've mentioned that there is no issue in account side also integration is perfect and ads were loading before. Could you try once by enabling the Ad Inspector ? And then share the export request and response file generated from Ad Inspector to us along with app ID & ad Unit ID 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. Please check this Getting started with Ad Inspector video to troubleshoot the “no fill” errors.

Kindly provide the requested details via Reply privately to author option 

Thanks,

Hi,

Thank you for providing the requested information. 

I have executed our Google Sample project with the provided information, I have been unable to load the ads on my end. It has come to my attention that the error message "no fill" is being displayed in conjunction with your IDs. 

The Error code 3, no fill error means that the ad request was successful, but no ad was returned due to lack of ad inventory. You may check this AdMob Error Codes & Logs for more information on different kinds of errors. 

Upon checking your AdMob account, I observed that the app-ads.txt file has not been configured yet. Please use the following help center article to Set up an app-ads.txt file for your app and Resolve issues with app-ads.txt. 

This is more of an Ad serving concern rather than anything specific to the code implementation of the Mobile Ads SDK. The next step for you would be to reach out to the Product support team for further assistance regarding the ad serving concern. The Product Support Team is well equipped to handle your concern effectively.

Thanks,

Hi,
Regarding your concern, you may benefit from reviewing the help center articles on Account issue FAQ.
Kindly be informed that our support channel can only assist you with regards to Mobile Ads SDK implementation and technical issues. As your concern is more related to the Account side rather than Google Mobile Ads SDK. So I would recommend reaching out to the Product support team as they are better equipped to address your concern.

Thanks,
