pvp not functioning

[flarewolf56]

current version is 2.5 of masterduel single player works fine but when trying to set up wan and play with my gf (i have ports forwarded already and do so for many games and even set up ones for masterduel) when launching ygomasterclient.exe it does not launch ygomaster.exe and tells me there was no response from the server aka ygoclient.exe does not launch. however if i disable multiplayer in the settings.json the game runs just fine. please fix?
