Fail to run xrdp, controlling a kali linux device from an ubuntu device

[Jenner]

I'm trying to control my Kali Linux laptop via an Ubuntu machine using xrdp, but I'm getting the following error:

This;
client_ip=::ffff:1

tells me that XRDP is trying to use IPv6 have you an IPv6 set up on your network?

I suspect your local machines are connected over IPv4 on your home network, so you need to set up XRDP to use this instead..
Have a look at the command line manual as it suggested..

man xrdp
