xrdp vnc not working properly

SUSE Linux Enterprise Server SLES Configure-Administer
1

Hello,
I just installed a 60 day trial of SLES 15. I choosed SLES for SAP install option and left packages at the default values.
Now if I connect from Windows 10 via RDP, the connections almost all fail. Maybe 1 of 10 work, mostly after reboot. mstsc is setup to use only 24 Bit color depth.
xrdp and sesman log level is set to info. Firewalld is shutdown (machine is already in DMZ).

Definitely make sure the color depths match between the client and the xrdp server - that has been the single-most frustrating error for me.

Try disabling things like remote audio, printing and clip-board
