every time i want to our server the screen freez at loading treeain for a while and then say "internal exception java net socketexception connection reset". 

i tried restarting my router + pc + the launcher, i uninstalled and re-installed java and made sure its up to date, i downloaded the latest driver, deleted mineraft file and downloaded it again. made sure the firewall are allowing the java in private and public and changed my DNS. 

im lost at this point i can only play single player, other people can access the server but i cant.

version 17.1
