Issue with Azure Public IP access

Hi after rebooting my virtual machine - the services available at http://52.189.100.194:8090/controller which is the public IP of my VM stopped working. Turned off iptables completely. This service was fine a while ago - don't know what went wrong. Please help with the troubleshooting.
