Multiplayer Issue

[up8328]

Hello,

I'm new here and looking for some advice on what to do. So I'm having an issue with modded mc and don't know if this is a java, internet or forge related. I can connect to most servers perfectly fine without issues, yet when I connect to another server I get this "java.io.IOException: An existing connection was forcibly closed by the remote host". The hosting company says it has to do with my connection, but i've explained to them every other server I connect to I have no issues whatsoever. Tried older versions of java and the most recent. I know this is mostly a forge support forum, but any assistance would be greatly appreciated to help pick my brain a bit.

You can download the log here, since it was too long for pastebin. https://www.dropbox.com/s/ejz6zpyd51c291m/latest.txt?dl=0

Again, thank you very much if you can assist me getting down to the source issue.

Is this your own server? The issue may be with tinkers construct.
