Mobile suit gundam online extremely lag

It was fine before 11/13 but in these two days,it become extremely lag with mudfish. The RTT reach 3000 so frequently almost every minutes. I tried different servers but all of them have same problem. I also tried others free VPN e.g. VPNGate, it’s less lag than mudfish. However the free VPN are so unstable. What I suppose to do?

Did you try to change a mudfish node based on FAQ - Nodes section for your game item? If you’re using the advanced mode, please start with the basic mode.
