I tried about 8 JP Asia free public nodes and Full VPN mode doesn't seem to work at all using Mudfish v4.6.0 and Windows 10. Not sure if it's a node limitation or a program issue. Mudfish nodes still work properly.
Clearing the node whitelist fixed the issue. Thanks!
Cool! :-) I hope now everything goes well with mudfish. Please let me know if there are any other problems.
