Bad Packet 86 Error

[DarkGuardsman]

I've been running a server for a while and have never run into this issue before. As well the company i rent the server threw(fragnet) has never seen this error can't help me more. I've done 2 clean installs of my server to try to resolve this issue as well other normal error resolution when it comes to mods. Nothing seem to work and since i'm running forge i though to ask here.
