DC after 5-10s on server I used to play ( internal exception )

[Heavic]

I was playing on server for 3 days. but today when I tried to join I always get kicked after 5-10s in lag and then it shows me this: internal exception: java.net.socketexception: Software caused connection abort: recv failed

Any ideas what to do with it?

Add. info: When I try to conect via mobile phone, everything works "fine" (1s delay). So it probably our internet connection, but wierd is that I played on same server with same internet 3day ago :(
