I really need help..! My server was working fine yesterday, but now everyone (include me) gets timed out! The port is forwarded to the IPv4, minecraft & my internet is up, and I can only connect with my IPv4 adress. I have removed Dynmap to see if that worked, set online-mode=false and more.. Can anyone help me please?
Remove the value from server-ip in the server.properties. Are you able to connect through 'localhost'?
