Tyk-Dashboard service doest not open port 3000

I run this command for the bootstrap.sh (xx.xx.xx.xx is my public ip, i do not have a hostname) :
sudo /opt/tyk-dashboard/install/bootstrap.sh xx.xx.xx.xx:3000

And when i check the logs, tyk-dashboard.stdout is empty and tyk-dashboard.stderr have this line :
time="Aug 4 11:23:15" level=info msg="Using /opt/tyk-dashboard/tyk_analytics.conf for configuration"

When tyk-dashboard service start, he must open port 3000 itself ?
