Hi @bigt1973,

Welcome to the community.

I am sorry to hear you're having problems with the Play Store

Can you please let me know what troubleshooting steps you have already taken so I don't have you repeat anything you've already done.

Hi, I followed the six steps in the troubleshooting guide which included checking storage space, switching on airplane mode and off again, switching WiFi off and on, resetting my router, force play store to stop, clear data and cache, update play store and finally restart my device. None worked.
Any help gratefully received
Thanks

@bigt1973,

Does this error only happen when you're connected to WiFi? Does it not happen on 4G?

It only happens on WiFi.

Just noticed that my phone is also identifying itself not as an X but as a z3 on email footers too!

@bigt1973,

That would indicate the issue is with the Wi-Fi you are connected to. Does this happen on all Wi-Fi connections? Just one?

Hi, yes it appears to just be my WiFi... Any idea what it could be?

@bigt1973,

Are you experiencing any other problems on your phone while connected to this wifi connection? Can't browse, view youtube etc? Do any other devices on this network have any issues?

Turns out my daughter can't download apps either on her Xperia Z3 but we can access pretty much everything else. No other loss of functionality

@bigt1973,

Thank you for this information. We can isolate it to your modem or connection in that case. If you haven't already, restart your router and try again. Also try to forget the network on your phone by giong to Settings > Wifi > Tap and hold the connection and choose forget > Reconnect.

Hi, I've done both and it's still not working. Does that mean it's a modem problem? Thanks

In case I hadn't mentioned previously, I can't update apps either. Thanks

@bigt1973,

Because it is only happening on your home WiFi connection and no others, and that it does not happen on mobile data, and is happening on multiple devices, leads me to believe that the modem or the internet connection is where the issue lies.

I recommend you contact your internet service provider for further assistance. There may be a blocked port that the play store uses.

I have had the same problem and finally solved it by changing my network configuration.

In my case, I had to change the DNS settings on my network router.

The background for this, is that I have previously replaced the default DNS servers from my ISP - with Comodo Secure DNS*. And for some reason, it is blocking some of the security features introduced in Google Play. It's just an opinion - but I suspect it has to do with Google Protect.

I propose the following actions for others to try out. Please refer your ISP/manufacturers documentation on how to do this, as this will vary greatly between devices:

Logon to your router's** admin interface.
Change the DNS servers for your WIFI and/or LAN to Google Public DNS***(IP addresses 8.8.8.8 and 8.8.4.4).
Restart your router.
Wait for the router to reboot, and restart your phone.
After your phone's reboot, connect your phone to the WIFI(if it have not already).
Make sure to deactivate Mobile Data network - remember you are testing the WIFI.
Open Google Play and retry to download a new App(or update an existing).
If this succeeds you are good:-)

Hope this helps.
