Very clever lad....well done you...:smileywink:

Doing a test in your own is more realistic than reading any post.

Not if you make data input errors and don't recognise them.......like you did with that link

I fixed the typing errors now.

Why don't you just download the version that works in the UK and log in to your account on it?
The Japanese version is not meant for use in UK so you won't get any support on UK networks.

The problem is caused by broken WebSocket on O2. It relates to other applications such as HTML5, and is a violation of global standards, not only this game, and there is no restriction on where can a player play this game, like a person travelling around, and they never forbid you from downloading in one place and playing in another place.

Well, have fun proving the violation, on the game not meant for this region, on the phone not meant for this region where you've slapped who knows what vpn's on top of the o2 apn.
Cuz I just tried the version meant for this region and it worked fine.... Funny that.

That VPN is in UK, but what that VPN is is unimportant, because it works elsewhere in UK like Public WiFi and a landline connection without a VPN.

If you have downloaded that game, try the multi-player mode and take a screenshot with signal bar because I only encounter problems when playing in multi-player mode.

I never try that version in UK Play Store. When you are a person travelling around, you can only register on only one server, you can only use a phone from one side, and you can only download one version based on the location.

Anyway, the packet logs are analysed by the following setup.

1. A Windows notebook with an ethernet adapter and the ability of running a WiFi hotspot.

2. My phone connected to the WiFi hotspot hosted by the notebook.

3. The notebook is seperately tested for two cases, an ethernet connection to a landline connection and a connection to another phone SM-N9005 with the O2 SIM inserted.

4. The packet is captured using Wireshark which is used to follow the TCP stream and discover a wrong response code from the server when on O2 network.

All that, to play a game..
Have you verified with any other networks sim?

I would suggest enough Community time has been spent on this.

Hi @evantkh,

Did you run a diagnostic test with the O2 shop team as you mentioned before?

Not yet, but it is coming in the next few days.
