Players Can't Hit Players(Glitch)

So sometimes when 2 players are pvping they can hit each other but then all of a sudden 1 of the players can't hit that person. I know they aren't forcefielding or anything because I've been getting complaints about this happening several times, and this causes my server to have horrible pvp. Even players quitting because of it... Nothing in the log comes up so here is my plugin list:

Could you execute /ncp info <AffectedPlayerName> here and paste us what you get back from that command?

Are you sure that this player isn't cheating? He has quite a lot of alerts there and FastBreak is insanely high. Could also be an issue with a plugins so I recommend you to execute /ncp info on some other players also just to be sure. Also check that NoCheatPlus and CompatNoCheatPlus are uptodate on your server.
NoCheatPlus picked up cheat attempts in fighting of that player so it prevented him from pvping/fighting for a short period of time.

 

Well atleast now I know what plugin is causing the issue, is there any way to disable the prevention? Because players can just report it to me or my staff.

Yea you can simply disable the canceling of the Fight checks. All you need is NoCheatPlus 539 (or higher) and the configuration file I uploaded in the attachments.

The changes only:

WARNING: Using this configuration file will allow players to use cheats such as overpowered force fields and other! Use it at your own risk!

And btw: Those players look suspicious to me (too many NC+ VLs to be normal) so I rather be careful on what you do here. Maybe they try to make you disable parts of your server protection.
If you want to reset the config back to default again simply delete the config.yml and execute /ncp reload ingame or in the console.
