There are many reasons you may be experiencing a connection error when you attempt to open a virtual machine. One of the most common reasons is that our virtual machine backend is being blocked by your organization. This can occur if you are using a computer and/or network connection issued by your organization. If you are experiencing this issue, please ensure that the backend to the EPIC Cyber Range is whitelisted by your organization.
Backend: openstack.cyclone.tacc.utexas.edu
If whitelisting doesn't resolve your issue, please submit a support ticket: cyberrange@consult.tacc.utexas.edu
If you are a student, please inform your teacher and they will submit a ticket.
