I have a private server for my friends and I, and we played in the server today.... after a short time something happened and I closed it and re-opened it.
when I re-opened it the server didn't want to show up as "online" even thou the batch(cmd) file said its running just fine.
I changed the ip address to 127.0.0.1 to see if the server has any trouble of turning on, and it worked just fine.
changed it back to my IPv4 address and it didn't show up but was running,
then I changed it to my Public address cause' I told myself "maybe that's the problem?" and the server didn't want to turn on at all.
So I checked my ports, and they are fine, I re-installed java, and its just fine.
I think I did everything and the server still won't show up as "online" on my IP anymore (even thou it was a few hours ago!)
Does ANYONE know what's the problem and how to fix it?
your public ip won't work because you are inside the network, you connect to either the hosting machines local ip (if playing on different computer in same house) or LOCALHOST (127.0.0.1 is the same thing)
people outside of your house connect via the public ip
