Error code 3, how to solve?

[Marcos Paulo]

It seems my implementation of the code is done right, while testing on unity the test ads runs perfectly, but on deployed app on store I only get the following error:

Rewarded ad failed to load an ad with error : {
  "Code": 3,
  "Message": "Received error HTTP response code: 403",
  "Domain": "com.google.android.gms.ads",
  "Cause": "null",
  "Response Info": {
    "Response ID": "null",
    "Mediation Adapter Class Name": "",
    "Adapter Responses": [],
    "Response Extras": {}
  }
}
UnityEngine.UnitySynchronizationContext:Exec()

Any ideas on how to fix the issue?

Hi,

Thank you for reaching out to us.

Kindly note that the SDK just requests an ad to the ad server (E.g: AdMob), and I'm afraid that it doesn't have any control on fill rate / match rate and policy error of your app. This is more of an ad serving issue which is out of scope to our team. That said, we would recommend raising this to our Product Support team instead. The product specialist there should be able to assist you further on this.  In order to maximize the chances of receiving ads from the AdMob SDK, kindly make sure that you've fully setup your app-ads.txt file (https://support.google.com/admob/answer/9363762?hl=en&sjid=4434916467890728934-AP).

Thank your for your assistance. I will look into it.
