Flutter App Does Not Show Real Ads (403 Error)

[Berkay Şahin Aşkar]

Hello Dear advisor, 

I developed an app with flutter and I release the app on google play store. I validated my app in admob a week ago. When I tried the ads with test ids it works fine but after change it my real ad ids it gives an error HTTP Request 403. Received error HTTP response code: 403

I/flutter ( 1227): ResponseInfo: ResponseInfo(responseId: null, mediationAdapterClassName: , adapterResponses: [], loadedAdapterResponseInfo: null), responseExtras: {} I investigated every troubleshooting step and check but still the app is not showing the ads. Can you help me the solve the problem or inform me what is the problem. 

Thanks

Hi,

Thank you for contacting the Mobile Ads SDK Support team.

Please use the following help center article to understand Common reasons for ads not showing and use the Can't See Ads Troubleshooter to debug the issue.

Kindly note that Received error HTTP response code: 403 means, AdMob servers rejected the request. 

Could you kindly provide the below information via reply to author option for further investigation:

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

Thanks,
 

Mobile Ads SDK Team
