Every time I go on a server I am greeted with huge amounts of lag and a significant delay in actions such as opening a chest, but nobody else experiences this lag. Usually I can stay online doing very little for twenty or seconds or so before I am disconnected from the server, sometimes I'll be able to play for 10-20 minutes before I start disconnecting frequently again. I'm greeted with "Internal Exception: java.net.SocketException: Connection reset" and this in the console:

This only happens in TPPI, every other modpack has worked fine. I want to say this started in the most recent update, because on launch it worked fine. Anyone know what might be wrong or how to fix it?
