Confused as to why you think this is enderio i see nothing in the log about it being enderio. Do you have a modslist or a pack name?

I'm sorry about that, I have seen that the exception was appear after

Sending server configs to client for com.enderio.core.common.config.ConfigHandler

Plz wait a minute, I'm going to check whether is this a problem with EIO

I apologize for my own recklessness, this is not a problem with EIO, I found that I couldn't connect to the server even I have delete the EIO.
Sorry to bother you, I'll find the problem.
