The xrdp service is failing after a restart, with the following errors:

```
sudo systemctl restart xrdp.service
Job for xrdp.service failed because the control process exited with error code.
See "systemctl status xrdp.service" and "journalctl -xe" for details.

```

When I re-install it, it is working, until the next reboot.
option 1: `sudo apt-get purge xrdp && sudo apt-get install xrdp`
option 2: `sudo apt-get purge xrdp && sudo dpkg -i ./xrdp_0.9.4-1_armhf.deb`

I tried option 2, because I read that there is a problem with xrdp 0.9.1-9, so I downloaded a newer version.

The xrdp-config is unmodified, also it is working fine until reboot. That means I am able to connect to the Pi with no problems. Same with my modified config.

Right now i use this workaround after reboot, but i want to know what exactly causes the error:

```
apt-get purge xrdp --yes && dpkg -i /home/pi/Documents/xrdp_0.9.4-1_armhf.deb

```
