[SOLVED] Mopub banners on pixel 2

I am using mopub advertising, and have some troubles with Native banners on one of the devices, pixel 2 with 10 android. On other devices everything works fine. To fix this bug, I have updated library to last version 5.9.1, but it doesn't help me When I am trying to test Mopub sample application, everything works fine. ad unit id: 11a17b188668469fb0412708c3d16813

I init sdk with Activity context, and using something like this:

MoPubNative moPubNative = new MoPubNative(context, adUnitId, moPubNativeListener)

In the MoPubNative.MoPubNativeNetworkListener callback, I got onNativeFail

In the log, I see this:

Initialized adapters:
    No adapters initialized.
