Description and relevant errors:

Startup log: https://pastebin.com/ff9jy9GP Paper: Paper-146 (MC: 1.15.2)

I have been running paper for months. Then added Flamecord to the folder and booted with that as the .jar. The reason behind this was to check if someone was using bots + null packets as recommended by someone. Did not boot, reverted back to Paper-146 (MC: 1.15.2). Getting ProtocolLib disabled now.

Possible error: (Lines 131-137)

Solved,

This plugin was preventing it: https://www.spigotmc.org/resources/2ls-exploitfixer-professional-server-antiexploit.62842/?__cf_chl_jschl_tk__=50207f89143b76c7ca46ae88473455e9f50a01a3-1585844278-0-AY9vvvWYM0DW4kMK-XnCc-afGHRgDW4z7cLmOJPztWUwQFhGGxt_l8vjJJpGwhDpK62CEiYSOSYkboLoR9irPIOBHEnquD2HC65lJgwcJ8gT_aBFVlQ9eeImMgUs6tJu2brprRpNh-kwTP_GKtlrsfj9EgmXOjz2bBDjUsLTSGhDJHQGfokLVFC_bfo2-rHh6ydAzqV5kuwfxY8Wts1zuQP0o41bRSP3FV9SM-qVDJ3Tk4huU887X1y3bFr115AOdDUnmCLv8EHeN1LfirRA3WWLa0A95HkESRIcegiRFMk2XwTglMVJLo6ocIn0lW-GNOxxPPhRysETW76Xs7lbC0sHGtIQZp-vrvWXvVts6Yqb
