@AcExLegends, this indicates an invalid host IP. Do you have the IP value in server.properties empty?

 

@Tecno_Wizard
This is what I have right now:

Change server-ip=172.2.29.76 to server-ip=

 

@oceantheskatr, to be perfectly honest, idk why bukkit put that in there in the first place. Clear the IP and everything will work perfectly again.

 

I know right?
