according to this thread : https://forum-narutoen.oasgames.com/page/show-post-43729-1.html

serverS1353 HK has reached 60 days old. and i think there's a problem cause it still not crossed yet.

we can't do training ground event and Cross-Server GNW. even our SWB and Matsuri event can't challenge the other server player.

the server seems died there. we can't find a match in SWB and Matsuri for 2 months.

who can fix it?

I need the CROSS SERVER actived on this server. thanks
