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. It would be helpful but can't guarantee it's always make goes well then you should notice that Lost Ark is pretty large and it'll consume doubled if you download it through over a node. Your computer <-> node <-> the game server Amazon EC2, Twitch and Mudfish
