Honor 9 fails to update apps over Wi-Fi There is a new Huawei Honor 9 with Google services pre-installed.

When I download/update an app via wi-fi it gets "Downloading..." for a long time and then it finishes as:


  Can't be downloaded. Try again, and if the problem continues, get help troubleshooting. Error 503


Other phones/notebooks consumes the same wi-fi internet without a problem. Honor's Chrome can access internet normally. Google Play app can access wi-fi internet too (loading app info and pictures) except the one thing - downloading/installing an app. There is no such error via mobile data.

To make the things yet more complicated I am able to install certain apps but the majority still fails.

I cleared Google Play cache. Also the wi-fi permission is given to every app listed.

Model STF-L09 / Build STF-L09C10B170 / EMUI 5.1 / Android 7.0
Resetting my router to the factory state solved that mysterious problem.
