lost connection: Disconnected

When I try connecting to a server I created I get this error in summary:
net.minecraft.util.com.mojang.authlib.GameProfile@31ae6f29[id=<null>,name=MindReader,properties={},legacy=false] (/25.19.244.225:50766) lost connection: Disconnected

Here is the full server log:
