Opening Chests at the end of a dungeon run

[HypeCronos]

Please help.. how do I fix this problem? I can't seem to open chests in ever dungeon run.. I played BnS CN server last year and I can open chests at the end of every dungeon.. is this a bug ? an update where opening chests aren't now part of the game? or only a premium member can open chests?

Yes I have basic keys.. Usually basic keys could open chests .. Then when I tried NA server I can't even open any chests since when I started playing this server
