I can't join minecraft server by some bug

hi, I am a minecraft player at south korea.

When I try to join server in minecraft,

Internal Exception java.net.SocketException: Connection reset

this bug occurs.

1. I tried to refresh my dns with typing
   ”
   netsh interface tcp show global

netsh interface tcp set global rss=enabled

netsh interface tcp set global autotuninglevel=normal

“

but it didn’t worked.

1. i changed version of minecraft(1.20.1 / 1.8.9 etc…)

but it didn’t worked.

1. add “-Djava.net.preferIPv4Stack=true” when launching minecraft.
   

yeah it didn’t worked

1. delete hamachi and used another vpn.
   

also didn’t worked.

1. i used my notebook instead of my computer.
   

this didn’t worked.



i don’t know what to do now. I wasted 3 hours trying to fix this stupid game.

I wish I could get a solution for me.
