Ad failed with error code 0 - onAdFailed error code 499

[sametguzeldev]

Hello.

I am testing your apk on EMUI 8 and Android version 8 tablet that has HMS Core 6.0.0.304.
I am getting Ad failed with error code 0 - onAdFailed error code 499 for all ad types.
It works for EMUI & Android 10 Version but doesn't work below that.
When I check the official page it says EMUI 3.0 or later is enough.

Here is the log:
com.huawei.hms.ads.sdk-logcat.txt

Thanks in advance.

It shows that your network failed in your log, requesting ads requires internet access.

[sametguzeldev]

I do have a working connection. It did popped up two consent pop ups and I've accepted them. I can make a video recording if needed.

[Mike-mei]

Sure, please provide your video record.

[sametguzeldev]

The video was more than 10MB so I could not upload that to here.
Please watch it from here

I show my Wi-Fi settings and I browse through AppGallery at the start to prove that I have an active working internet connection. Then I open the application and you can see the results. I accept two consents but still ad error code 0.

Hello there. I will be sending it today!

[sametguzeldev]

Here are the logs you've requested. hwads.txt

I've done the same steps as the video and only in the app. Tried to load banner and Interstitial Ads.

It shows in your log: countryCode by ro.product.locale.region is:US, is your local area set to the US? The area should be set to other regions except for the US.
Method for setting regions in your phone: settings-> system -> language and input -> language and region -> region

[sametguzeldev]

Hello again.

I've gone into system > language and input > language. But I don't see anything related to changing the region. I can only change device language. My AppGallery region is set to Turkey.

I've also used adb shell getprop to see it and as you've said it says it is the US.

But I don't know how to change it. I tried to change it with setprop but did not work.

[Mike-mei]

Click the language here then you can see the button to change region.

[sametguzeldev]

I've already checked that before sending it to you but only has an option to add a language. Currently UK is selected.

The three dot on the top right corner only offers to "Remove Preferred Language" fyi

[sametguzeldev]

Any updates on this ? 😄

Please insert a SIM card (except US) into your phone and try again.
