I was using the League of Legends Japan server yesterday and getting a good ping about 100ms. Today it is at 500? Do you know what the problem might be?
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.
Thanks. It seems like settings switched to advanced mode. I don’t recall doing this… Back to basic and it seems to be working fine again.
Great customer support by the way.
Cool! 
I hope now everything goes well with mudfish. Please let me know if there are any other problems.
