Windows remote users attempt to login to linux suse ebterprise desktop

1

Hello there.
I run a Linux Suse 15 SP6 which provide remote connection to windows users thru XRDP. Currently have configured limit connections to 200 (opening var /etc/xrdp/sesman.ini):

[Sessions]
;; X11DisplayOffset - x11 display number offset
; Type: integer
; Default: 10
X11DisplayOffset=200

Usually 15-20 users attempt to login, but the new ones who tried, receive a sesman message says: connecting to sesman on 127.0.0.1:3350
sesman connect ok
sending login info to session manager. Please wait…
login failed for user (userID)
How can I fix this ?
Thank you.

I checked the log in xrdp.sesman.log and I’ve found this messages:

What could be the issue? I have already reduced the number of sessions to 100 but still persists.
