If you try 9965 and it's not working, try 8889.
Here, since you already opened ports 8888 and 8889 as TCP ports on the firewall, we can now configure and drop IPV4, just like we did on the login server.
Follow the tutorial below.
# Rmi connection host.
network.rmi.host = (The IPV4 of your virtual machine or personal computer.)
# Rmi connection port.
network.rmi.port = 9000
# Host for the server binding.
# Default value: 0.0.0.0
network.host = 0.0.0.0
# Port for the server binding. EACH SERVICE HAS ITS OWN PORT
# Default: 8889
network.port = 8889
" network.rmi.host"I'll explain, basically you need to put your ipv4 here, since players will connect to it.
As for port 9000 you don't need to open it. But as I said at the beginning, you need to open ports 8888 and 8889. Never open port 27017, it is your database location, if you intend to open a server online for everyone to come in, never open port 27017, because if you open it some people like me will connect to your port 27017 and i will put my account as administrator account.
Also in relation to the ip "0.0.0.0" you do not need to change, since it is an ip that redirects, so it will automatically redirect the ip to your ip.
