xrdp fails to start

[John Rose]

Ubuntu 22.04 Desktop 64 bit AMD. xrdp v0.9.17-2ubuntu2. Tried to start xrdp with 'sudo systemctl start xrdp' but failed. This is confirmed by requesting Status. Extract from attached Terminal output:
Aug 16 09:37:32 Demonstrator xrdp[339100]: [ERROR] g_tcp_bind(7, 3389) failed bind IPv6 (errno=98) and IPv4 (errno=22).

Could this page https://community.spiceworks.com/how_to/195154-how-to-set-up-and-use-remote-desktop-connection-in-ubuntu-linux give a solution (shown below) to this bug even though it applies to Ubuntu 18.04 and the bug gives a slightly different problem?
Solution is:
he problem is related to the xorgxrdp package and the particular changes in Ubuntu 18.04 that caused xrdp capability breakage. In this guide, we use Ubuntu 18.04.2 to configure xrdp. To solve the empty blue screen problem, install the relevant xorgxrdp-hwe by executing the following command:

sudo apt-get install xorgxrdp-hwe-18.04

To check the current version of Ubuntu, use this command:

lsb_release -a

Restart the xrdp service (daemon):

sudo /etc/init.d/xrdp restart

After the required package is installed, open the RDP client. Then, try using RDP to connect to your Ubuntu again.

Used the webpage at https://orcacore.com/install-configure-xrdp-ubuntu-22-04/. xrdp got further but it fails with:
john@Demonstrator:~$ sudo systemctl restart xrdp
Job for xrdp.service failed because the control process exited with error code.
See "systemctl status xrdp.service" and "journalctl -xeu xrdp.service" for details.
john@Demonstrator:~$ sudo systemctl status xrdp

I've just tried the changes outlined at https://pimylifeup.com/ubuntu-xrdp/. These are:

After stopping the xrdp service & starting the service again it failed to start properly, its status is:

Mind trying with Ubuntu 24.04?
