I added "essentials.tpacancel" to player and they still can't use command /tpacancel (no permission message). I'm using LuckPerms permission system.

What appears in the console when you run the command?

@md678685 I am having this issue as well and nothing appears in console it simply says no access
I have tried the following nodes to deny it and none work
essentials.tpacancel
essentials.tpcancel
essentials.tpa.cancel
essentials.tp.cancel
essentials.canceltpa
essentials.canceltp
essentials.cancel.tpa
essentials.cancel.tp

Could you run /ess debug and try running the command again?

@md678685 @MsArtix I tested with PermissionsEx (Essentials 2.0.1-b547, spigot 1.12.2); I was able to have tpacancel without having access to tpa, tpdeny, and tpaccept.
I blame LuckPerms and a potential cached data problem within LuckPerms for the original issue?

@MsArtix Which permissions plugin are you using? Essentials.tpacancel is the permission node.

I have same problem and I'm using LuckPerms.

@MsArtix @Tarka-Dhal Could you run /ess debug then post the console output when you run /tpacancel from in-game?

Closing as the original poster's account has been closed and other people facing this issue have not responded. If you encounter this issue, please reply with the console output of a player running /tpacancel after you've run /ess debug.

If anyone else ever experiences the same issue, the fix is applying this perm to any group:

essentials.tpdeny
