Failed to create IPv6 VNC socket: Error binding to address: Invalid argument

[ghost]

I have listen-address=10.1.2.3 but it still tries to use IPv6 for some reason.

I'm having the same issue. Did you figure it out by now?

Did you tried to completely disable IPv6 on host?

net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1

I have the same issue (but can't turn off ipv6 to fix it). It for some reason tries to use ipv6 even if listen-address is ipv4.

It's probably a bug? @ghost @repomaa did you find a fix?

Same issue here, disabling ipv6 does not help.

My config:

[VNCServer]
enabled=true
command=Xvnc -rfbauth /etc/vncpasswd
port=5900
listen-address=localhost
width=1024
height=768
depth=24

I tried with listen-address=127.0.0.1, 0.0.0.0 & my public IP with the same results.

Same error. And I need IPv6.

I have created a hostname resolvable to both : IPv6 and IPv4.
ping works correctly, with the same name it pings IPv6 or IPv4 with matching switch..
lightdm still cannot start VPN:
