Banning players not working

[c0dingnoobi]

I made sure this issue is not caused by my server environment. Tested on a new environment and ran titanium with default config and without plugins. Banning a player using /ban only kicks the player with the ban message. The player can rejoin immediatly. When banning a player he gets added to banned-players.json.

  }

Player has no operator permission (or any permissions at all). Reproduceable regardless if command is issued from console or as player command. Using 0e28735d8ee52f3133f1795919612d17e8a5ddf6 (123th devbuild)

Is your server connected to a proxy?

Forget it. It doesn't make any difference, I thought that proxies might manipulate uuids, but that's not the case. I compared the standard method of Spigot and Titanium to check if a player is banned, and it seems to be the same. You can check it yourself, just check the attemptLogin method in PlayerList, you'll find everything I checked there.

Sorry for late response, but on standard spigot/paper everything works fine?

More info:

    @EventHandler
    public void onLogin(PlayerLoginEvent playerLoginEvent) {
        getLogger().info(playerLoginEvent.getResult().name());
        getLogger().info(String.valueOf(playerLoginEvent.getPlayer().isBanned()));
    }

when I join after I ban myself returns: [21:45:35 INFO]: [Test] ALLOWED -- Result [21:45:35 INFO]: [Test] true -- If the player is banned

if I remove the ban using essentials unban or minecraft pardon command the user will not be removed from the banned-players.json but then if I join the message will be: [21:45:53 INFO]: [Test] ALLOWED [21:45:53 INFO]: [Test] false

I believe an issue like this existed in paper 1.9 and fixed in 1.10? I'm not sure tho
