Fatal error: One or more hosts failed while executing task 'instance_liveness'

I am running the demo at "https://github.com/CSL-KU/firesim-nvdla", and now I just in the "running a single node simulation" step, but when I run the commad "firesim infrasetup", error show as follows:

`FireSim Manager. Docs: http://docs.fires.im
