Android devices behind a Guardian web filter cannot access the Google Play Store.


The Google Play store application uses port 5228 and does not go through a web proxy.


Add the following domain to your authentication exceptions and whitelist rules:


In order for Android devices to be able to access the Google Play store, outgoing access to TCP and UDP port 5228 will also need to be allowed from the network the Android devices are connected to.

However, there are multiple applications in Android and iOS that do not use web ports and protocols — in order for those to work correctly, outgoing traffic on those ports will need to be allowed from the network the devices are connected to. It is recommended you contact the applications' support in order to find these ports to add these to your firewall allow rules.
