What makes you think that your connection is okay ? Just because you can read manga ? Games and pictures are 2 different things.

Please fill this report form for me :

Platform (Browser/Facebook/Client) :
Server ID :
Character Name :
UID (If you are using Facebook account, you can find your UID on the bottom of the page. For players with OAS account : go to your profile - "change nickname") :
Bug Description :
Screenshot :
Operation System :
Resolution :
Your computer time-zone/Country :
Are you using VPN or not ? :

But I would still recommend checking your connection because most likely it is problem on your side.

Hello,

I got response from our team. This "offline" problem is problem on your end, to be more specific it is your network. I have been told that you should clear your cache and try to use a VPN because you are playing on US East server but your location is GMT +7.

One problem per thread.

If you have your own problem, please post it in your own thread, this thread or you can message me with details.
