So I just got my hands on an Alpha 1.1.2_01 server .jar (because why not) and...I'm not sure how to connect.

See, in the server.properties, this is all I get:

#Minecraft server properties
#Sat Jan 23 17:56:19 CST 2021
online-mode=true
monsters=false
server-ip=
server-port=25565
max-players=20
level-name=world

See, the server IP is empty, so there is no way to connect AFAIK.

This is the server log, nothing too special here, so I'm just gonna put it here if it might be of use.

Alright, so I solved THAT, but I have a new problem. Whenever I try to connect, it says Connection lost with the following error

Internal client error: java.lang.NullPointerException

In the server log, it even says I lost connection (I tried connecting twice)
