OS Name/Version:Ubuntu 18.04.4 LTS Product Name/Version:AMP / 1.9.9.0

Problem Description:

created a new instance for minecraft java after a clean install of linux on my HP Vsphere box. The system spins up fine looks to be running. but i can not connect my client minecraft game to the server WAN or LAN address is rejected. There is nothing in the server side logs to show a connection attempt was made.

Actions taken to resolve so far: manually create firewall rules in ubunutu :- no effect

recreated the server from scratch :- no effect

changed the port bind in instance > config > Minecraft > Server IP (was loopback now any ipv4) :-no effect

Change the port binding to 0.0.0.0, then start the MC server. After that open up a new shell and run ampinstmgr portsgiving it the name of your Minecraft instance when asked, and post the result.

turns out this is a problem with ipv6 where its binding the port to ipv6 requests rebuilding on a new OS to work round this issue
