When ever I or anyone else on the server uses a Celestial gateway to teleport, The entire server crashes and gives everyone the crash "java io.ioexception forcibly closed by remote host". I don't have any crash logs, since I'm not the owner of the server.

Need to get logs from the server owner, then. Sounds like socket disconnection based on that error message, but it's literally guessing on source.

@Piman801 needs logs or I'm closing this, because there's literally no information to operate from. The error is a socket disconnection timeout, need to see what precedes it to know what is going on, and what's sending enough data it times out the connections.
