pls fix it I can not open the game

As workaround you should use one of methods at Unsupported Games. And if you want to see it officially at Mudfish, please send me some game packets using Packet Capture with Mudfish link while playing the game with Full VPN mode.

I did not ask about Full VPN mode or Unsupported Games I ask about blade and soul Eu server disappear from the list pls fix it now I can not use the game 2 days now

Did you check "Blade & Soul" game item instead of "Blade & Soul: Hongmoon Rising" game item?  It's different each.
