If you have Android Kitkat, probably, being connected to a Wi-Fi network, you will have suffered a bug that is already recognized in the latest version of Android.
How to solve it
The error tells us that the session has expired, instantly disconnecting from this network. The error may be due to Android checking the status of the connectivity of our device, and if it does not reach the client, the connection is restarted. If you suffer from these connection cuts in your Wi-Fi network, you can very possibly solve it with this little tutorial. We have two ways to solve this problem. One is accessing the router in which we are connected, or in the Wi-Fi configuration of our terminal, which is possibly the most used, especially if we are not at home or work and we do not have access to the router. In this tutorial we will show you the second option, thanks to a user from XDA. Also avoiding blocking the site clients3.google.com, which would directly affect Google Play Services. Let's see how to fix it.
- We go to Settings - Wi-Fi - and we press and hold for 2 seconds on the connection that gives us problems, to mark the option «Modify network»
- We check the box «Show advanced options»
- We change the proxy settings to "Handbook"
- We introduce as proxy host name the value «192.168.0.1» and as port one of the following: 8080, 3128 or 80
- We save the changes
- We turn off the Wi-Fi connection, turn it on again and we should no longer see the error message
- We repeat the first two steps and now we change the proxy settings to "None"
Now we should no longer have any problems with this Wi-Fi connection. We hope it has been helpful, and leave us in the comments if the problem has been solved.
