Google Account looses login

Hello everyone,

we currently have a problem with our devices and the google play store.

When we enroll our devices we manually enter a google account. It is the same for every device.
At first everything works fine and we can install the necessary apps out of the play store.

After a while (not a set amount of time) you need to login again with the google account.
When trying to login this time though it does not work. After "Checking info" it says:
There was a problem communicating with Google servers.

I analyzed the problem with our network department.
There is no traffic at all when trying to connect to the google servers. The connection seems to be blocked by the device.
Other Websites and apps work fine though and the traffic is visible.

When using a different wifi the google login works again.
In our company Wifi we use PEAP with MSCHAPV2 as second phase authentication.
Furthermore we use a proxy with an auto config file.

Is there any setting I could have missed or is this a problem anyone of you had before?

Some further infos:
Devices: Samsung Galaxy Tab S2 with Android+ profiles
Mobicontrol: 14.2.0.2894

Thanks for the help

How many Tab S2 do you have altogether that all share the same Google account?

Do you have similar connection problem to Google server if only a small number (say 10 or less) are on-line at the same time?

We have around 250 active Tab S2 but a lot of them arent used that much.
I can't really tell how many do have the Problem but it will be quite a lot I would think.

I know it was a mistake using a normal Google account for all devices but we did not know better when we first implemented soti.

I have customers with over 2 thousand Android+ devices, each with a different corporate-owned Google account added to support Google Factory-Reset-Protection  (FRP) for device theft deterrence.   Though it took extra effort to create so many different accounts, it avoided problems such as

- the apps installed and other user's data on the device of one end-user being  accidentally synced to another device if any of the "auto sync" options of the shared Google account is erroneously enabled

- the possibility that Google suspect a Google account has been stolen if the same account is associated with a very large number of devices, which should normally not the case for a personal account.  

etc.

(It's good that Google has recently introduced the Enterprise FRP scheme, which allows pushing of a single Google account to hundreds of Android Enterprise devices with an MDM/EMM solution.  My customers thus don't need to manage a large number of Google accounts any more.)

As you mentioned that other apps can access the web on any of your problematic device, I don't think there is any networking problem.  Rather,  I suspect that your device cannot be connected to Google server because the server detects that there are too many devices associated with the same account accessing it concurrently.  Even if a person owns and put the same Google account in 20  or more of his/her Android phones and tablets,  the devices normally should not be all powered-on and active at the same time.  I am not sure if Google has implemented anything like this on their server, but I won't be surprised if they did.    If your tests confirm that the problem only surface whenever there are many devices active at the same time, maybe you need to consider replacing the shared account with a different Google account on each device instead.
