Please try to turn off FastConnect mode. FastConnect mode will NOT useful in UDP. This feature is for _TCP_ services.

I try to turn off FastConnect mode but still cannot connect mabinogi(japan) 

You should try to change to another Mudfish Node.

Thank you for your reply, I try that but still same.  Well,I use same node and try Full VPN ,then I can connect mabinogi(japan) again.I think that maybe they change some server IP when they go to maintenance at last Wednesday.

Please download and install latest Mudfish at https://mudfish.net/download then as workaround, you should use one of methods at Unsupported Games. And if you want to see it officially at Mudfish, please send us some game packets using Packet Capture with Mudfish link while playing the game with Full VPN mode. We need some packets to update a Mudfish item. image    ![image](https://image.mudfish.net/o/OtO8CY'/>
