ERROR: LoadError: IOError: connect: connection refused (ECONNREFUSED)

This might as well be impossible, but worth reporting. I'm on a headless Raspbian Lite on a Raspberry Pi 4 and:

Hmm... I've installed xserver, a windows manager, and a web-browser but I still get the same error... Not sure why?

Here are the details:
sudo apt-get install i3 xserver-xorg xinit firefox-esr x11-xserver-utils
reboot, login, i3 starts fine, test the browser - fine, start Julia with/out xvfb-run, but I always get the same error.

Maybe you can run Blink.AtomShell.electron() to find the electron in your system and try to run the elecctron in your Shell, maybe it will say some library are miss. Then just install them. At least i did this.

We need to detect/log stderr of the electron process if it quits unexpectedly (or maybe just add a flag to log electron's stderr to the console stderr, or something similar).

When I try to run electron, it gives an Exec format error on my RPi 4 running Julia 1.7rc1:

user@pi:~ $ /home/user/.julia/packages/Blink/mwJC9/deps/atom/electron
bash: /home/user/.julia/packages/Blink/mwJC9/deps/atom/electron: cannot execute binary file: Exec format error

[twavv]

Probably due to RPis running on ARM and Blink.jl always downloading the x86 version of Electron.
