A lot of ads not showing because cross-origin failed calls

[johny1...@gmail.com]

Hi,

Since I have added MopUp through mediation I'm seeing a really high amount of ads failing to load because of this kind of error

D/MoPub: Attempting to invoke custom event: com.mopub.mobileads.HtmlBanner
 I/chromium: [INFO:CONSOLE(2)] "A Parser-blocking, cross-origin script, https://www.googletagservices.com/dcm/impl_v36.js, is invoked via document.write. This may be blocked by the browser if the device has poor network connectivity.", source: https://www.googletagservices.com/dcm/dcmads.js (2)

Is this a problem my side? Something not configured correctly? A problem with AdMob webview? Or is it simply Mopub ads that are badly written?

Thanks,

Hello,

This might be ProGuard stripping some of your MoPub classes from your release build, so by the time the MoPub SDK needs to invoke your custom event, there is no such logic around. 

Do you have the appropriate -keep statements in your ProGuard config to retain MoPub's classes?

Hello,

Thanks for confirming that the issue persists with ProGuard disabled.

Could you send over a minified zipped project with our SDK and MoPub's, including the ad unit ID, so we can try to replicate the issue locally? 

You can use getMediationAdapterClassName() to distinguish from where a particular ad is returned at the time of receiving such log messages. That should help narrow the cause of the issue.

Hi,

After further test it seems that the problem 'also' occurs with Leadbolt. Yesterday my Impression dropped almost 40%.. As a result I have completelty disabled these two network from my mediation settings on AdMob.

This means even If i provide you with an apk you wont be receiving any ads from these network and probably you wont see these errors. Do you have a way of forcing the ads to come locally? If so please let me know how I can send the apk to you.

Thanks

[Vu Chau (Mobile Ads SDK Team)]

Hello,

Thanks for confirming. Rather than disabling the networks completely, I'd advise looking into your serving settings on your mediated networks (MoPub and Leadbolt), and ensuring your configurations are optimal for serving. This seems like a no-fill scenario, and disabling the network is not a solution. Sometimes frequency capping kicks in, and serving will pause momentarily.
