Can't access Docker container on exposed port from anywhere even localhost

I have been searching for an answer for this for days and don’t know the best place to ask for help, I must be missing something simple.

This problem is common to both my Fedora27 workstation and Ubuntuserver 16.4 LTS

I have installed Docker successfully and have some containers working but others cannot be accessed on or localIP:

I have disabled firewall and flushed iptables, amongst others I am trying to get a minecraft server running on 25565

"To simply use the latest stable version, run

docker run -d -p 25565:25565 --name mc itzg/minecraft-server

where the standard server port, 25565, will be exposed on your host machine."

However, the port is not accessible “can’t establish a connection to the server at”

Please help me understand what is blocking my port, this is doing my head in.

Would it be possible that your host’s port 25565 is already taken (previous attempts maybe)? Have you tried another port, something like 35565:25565? Then you should be able to access it like localhost:35565.
