Network connection error lollipop 5.1 update

[SilverMerlin1]

Yesterday I uploaded the lollipop 5.1 update to my z2 tablet through pc companion and everything seemed to work fine. However I get a network connection error in sony movies and the play store whenever I try to download something. It's odd as I can connect to the Internet fine through chrome etc and surf the Web can't seem to download on the device. I have tried this on three different wifi networks so it must be something to do with the device. Can anyone shed any light on this error?

I suggest that you try to repair the phone software using PC Companion..

Before repairing your device you may want to backup your information first. Check out this topic for more information on how to.

Hi @SilverMerlin

If you can connect to Internet and surf the Web using for example the Chrome browser, your network connection works ok.

I would try to clear the Play Store cache since this could be a reason of this error of repeatedly getting this network error message. To do this go to:

Settings -> App, scroll down to All apps and finally to Google Play Store app.

Open the app details and tap on "Force stop " and then "Clear Cache". Then restart your app.

I hope can be useful.

I'm at disposal for any question.

Best Regards,
