Before contacting the Support, please make sure that the port 22 (SSH) is allowed in the Security Groups associated with your instance. If this is configured correctly, please try to perform a soft or hard reboot of your VM. Lack of connection could have been caused by the expired DHCP. Rebooting will allow you to get a fresh DHCP session and everything should work fine.

The VMs are seen simultaneously in several networks, at least in your “private” LAN and in the public Internet. By default the public addresses (Floating IPs, 185.48.x.x) have no associated names. You may assign such names from your DNS domain or you may request a name from us (as an additional service). The names provided by us have the following format:

No. If we don’t associate a Floating IP to the VM, it won’t be routable from the internet. By setting an IP address using the process mentioned above, we will only see the interface address of the router attached to the private network (by default 192.168.0.1)

In order to make your VM accessible from the Internet, you need to use Floating IPs. Floating IPs in OpenStack are public IP addresses assigned to your Virtual Machines. Assignment of a Floating IP allows you (if you have your Security Groups set properly) to host services like SSH or HTTP over the Internet.
