I think the IP address of the server may have changed. The ping for Starcraft 2 (Taiwan) is incorrect. Mudfish will report 170-180ms but in game it is 360-380ms. In FullVPN mode there is no problem, it is 180ms for both.
Korea server does not have this problem (in game and mudfish both 180ms).
I have created packet data of FullVPN mode, please find this here: https://mudfish.net/forums/7/topics/67881
