it opens port 8080 to ipv6 only

[Barabba11]

Hi, how can I get rid completely of IPv6? it's useless for me and makes me crazy, unfortunately also your program what to deal only with that.
root@orangepizero:~/cyp# node .
no passwords.json found
1670083525741 ws2mpd attached to a http server { address: '::', family: 'IPv6', port: 8080 }

On /etc/sysctl.conf are already preset these lines:
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1

I rebooted, I don't know how can I kill it
I've an orangepi with latest armbian. Thank you

There is nothing IPv6-specific in CYP; the listening process is using the server.listen Node.js API with one argument. This means :: when IPv6 is available (which includes and allows IPv4 connections as well) and 0.0.0.0 when IPv6 is disabled.

I am no IPv6 guru, but judging from your log output, Node.js thinks that IPv6 is not disabled.
