Pendants (boilerplate and keyboard) trying to connect to IPv6 localhost while cncjs is only hosting on IPv4 address

[jochenderwae]

So, I was working on the cncjs-pendant-keyboard and I couldn't make it connect to cncjs (hadn't made any changes yet - or at least I thought so). To make sure, I tried out cncjs-pendant-boilerplate. This couldn't connect either.

So after some quality time with Wireshark, I noticed the pendants trying to connect to ::1 while cncjs was being hosted on 127.0.0.1.

I worked around this by disabling IPv6 completely on my system. I couldn't immediately find out how to force the pendant to connect to IPv4 address only.

Setup:
Raspberry Pi4
Debian GNU/Linux 11 (bullseye)
aarch64

I can confirm the workaround.
