Second realm error to launch


I did a test a second realm (on debian)
And I get an error each time that it puts “Bind address already use”.

Ok Address already use.
This is the BindIP I need to change, but by what?
The second kingdom uses the same version and is on the same server.
Level configuration, I have added a second in the realm database, which uses different ports.
Side configuration server is notified as “RealmID = 2”.

Just launch there is a crash with this error, and I do not understand what to put as IP.
How it works ?

Thanks for your help. ?

It does not help me.
I checked all of which is in the subject that you gave me.
I made a screen for specific error when launching the realm.
