Error during building example app: probably smth with websocket errno: -4039, code: 'ETIMEDOUT'

[ev-shamko]

Hi! I'm trying to prerender the CRA-example from this repository: examples/create-react-app/
But during build process i get this mistake.

And i get the same mistake while prerendering apps using react-snap and react-snapshot solutions.
So the problem must be on my side. Any suggestions how to fix this?

Here's the log:
