Mattermost server with docker

Hello,

I have some issue creating a server with docker. I did all those steps, and no one can join me on this server, it’s said that the connection with sever can not be established. I have changed the URL in the system console, restart the server and nothing changed.
Can you help me with this, I’m a newbie with docker, just installed for first time.

This is the steps which I followed
