It connects to wifi but when google or internet page comes up it says trouble communicating with google servers

Hi until you're WiFi problem is solved u can't access Google play ...try another WiFi to check if it's the tablet at fault or WiFi....cheers

is your tablet compatible to accept google

it means that when you go google , the internet cannot connect with the servers google use ( a server is a piece of electrical equipment similar to a post box where you put a letter addressed to google in ( using the internet addressed to google ) and the post man then collects that letter and places it in the postbox for google ( server)
If that post box is too full the postman cannot deliver your letter and that is a problem of communication
The action is that the post office then advises google to come and empty the mail box and then your letter is delivered
however if a lot of people are trying send letters at the same time or there is a electronic fault in the servers then you get that message so that you can use another search engine ( firefox etc ) until the problem is cleared

At the time it had something to do with one the the Google servers. It has been corrected.

Check your WIFI connection.

have you set it up to your wifi?0

Sounds like your wifi connection is down. If other pages will load, it's the server hosting this page which is down.

Either the website you're trying to go to isn't available, or you're not connected to the internet. Make sure you're typing the correct site, and that you are connected to Wi-Fi.

Try going Settings>Accounts>Google> Tap your account> Three dots in the upper right (or press menu button) "Remove Account" ... then read your account .. then if you want, clear Play store cache and data and try it

Are you sure you have a working Internet Connection on the Tab. If you are not connected to WiFi or using Mobile Data, the Tab won't be able to contact Google's internet servers to authenticate you. If you are connected, try disconnecting and reconnecting in case the connection is broken. If the connection is fine, make sure Google is accessible and try the login again.
Hope this helps, Alistair
