Please confirm that How to check the basic functionality works fine on your environment. It's a first thing you should test.

basic, and full vpn work fine, gamas to, but problem is on web site, if login and program working, site open work but if i want to login, give me error, if i closed program, login work (on web site not on game)

how about change the node or change Connection Protocols http://mudfish.net/docs/en/vpn/references/connection_protocols.html

i try to change server from  ge vultur 2 to alyun, i try full vpn mode, i try to change udp to tcp and difirent ports, problem persist, can login on web account  bladeandsoul.com, for login to site i need to close vpn and login, try yourself to do account on bladeandsoul.com and login in web site, with vpn (german servers) and other problem all time then start mudfish i receive message to open or closed networg sharing, (win10) and now i have network Nr35 , how to clear this shit

you mean  if using full vpn you can login on web ?

full or not, i prefer to use not full standard, game work normaly but have some stop working game rare on battleground, some days i receive error 1000, but ok the problem is only on web site, he working but if i want to login on my account on web site i will receive error - Something went wrong on our end. -Please try again in a few minutes ------- work only if i closed mudfish

The problem seems to be unfortunately difficult to solve.
