Cannot connect to external server when connected to Bluetooth Tethering

Hello guys,

I want to report that I can't connect to the external server because it says that I must connected to the WiFi in order to play on external server. D:
Well I'm using bluetooth tethering on my phone and then connected to my tablet. I don't use the WiFi tethering because bluetooth tethering use less power than WiFi tethering
And yeah, I got internet speed around 1mbps via bluetooth, doesn't it enough to do the multiplayer?

Thanks,
Antony Kurniawan
