Problem/Bug Whitelist working weird

Hey there, I've ran into very strange problem:
server whitelist doesn't let me in, even though I'm whitelisted...

Server console:

Code:

>whitelist add KruASe
[22:33:27] [Server thread/INFO]: Added KruASe to the whitelist
[22:33:29] [User Authenticator #2/INFO]: UUID of player KruASe is 15826d6d-62ec-3ba3-b57f-a82935484861
[22:33:29] [Server thread/INFO]: Disconnecting com.mojang.authlib.GameProfile@35224451[id=15826d6d-62ec-3ba3-b57f-a82935484861,name=KruASe,properties={},legacy=false] (ip): You are not whitelisted on this server!
[22:33:29] [Server thread/INFO]: com.mojang.authlib.GameProfile@35224451[id=15826d6d-62ec-3ba3-b57f-a82935484861,name=KruASe,properties={},legacy=false] (ip) lost connection: You are not whitelisted on this server!
>whitelist list
[22:34:02] [Server thread/INFO]: There are 1 whitelisted players: KruASe

This somehow fixed itself
Everything alright
