Login screen problem with console error!

Hi, I hope you are all fine

I'm having a console error and I really don't know why. I noticed that the ''login in...'' takes a lot of time, a lot more than before. Sometimes it just ends up by ''end of stream''. All my plugins are up to date, they all start properly.

List:
-Worldedit
-Whitelist
-LWC
-GroupManager
-Essentials, EssSpawn, EssChat
-dynmap
-anjosecurity
