Cannot get Ordt-viewer to work

[jyaghutiel]

./ordt-viewer -Dhttp.port=80 -DviewerHost=127.0.0.1 -Dplay.evolutions.db.default.autoApply=true -Dplay.crypto.secret=''

returns

[info] application - Creating Pool for datasource 'default'
[info] p.a.d.HikariCPConnectionPool - datasource [default] bound to JNDI as DefaultDS
[info] p.a.d.DefaultDBApi - Database [default] connected at jdbc:h2:~/ordt_viewer/regdb.h2
[info] play.api.Play - Application started (Prod)
[info] p.c.s.NettyServer - Listening for HTTP on /0:0:0:0:0:0:0:0:80

How can I get the program to read the IP address I enter? No matter what I enter for viewerHost, it always returns "Listening for HTTP on /0:0:0:0:0:0:0:0:80".
