How to set up Prax (Ubuntu's alternative to Pow) properly?

Question

linux

Hello!
Guys, please help me set up Prax for the project. Maybe someone worked with him?
It seems that everything was done correctly according to this manual: https://github.com/ysbaddaden/prax
I go to: myapp.dev and how to load everything except everything. That is, neither scripts nor styles are loaded ... only markup.
For all components in the devtool, the error is as follows:
Failed to load resource: net::ERR_EMPTY_RESPONSE
Maybe someone knows what I did wrong?
I will be very grateful for the answers!
Thanks in advance!
