Service mode: connection lost immediately after logging in

[SL9]

Host OS: Windows 10 LTSC 1809 17763.107
UltraVNC server 1.3.8.1

Steps to reproduce:
1. Install UltraVNC server as a service
2. Connect to the server with any vncviewer
(Tried: UltraVNC viewer in Windows, tigervncviewer in Linux, JumpDesktop in Android)
3. The MS Windows Logon screen is shown, type in the password and log in

Immediately after logging in from the logon screen, the connection is lost.
After reconnecting, the Windows logon screen is not shown, it'll directly goto the desktop

Not sure if this is an issue with the vnc server or the MS logon mechanism.

Server config file:

Thanks!

WIndows use a secure desktop for logon and switch to the user desktop after you enter the credentials.
VNC follow the active desktop and restart himself in the user desktop.

When you use the UltraVNC viewer and have the auto reconnect option active the reconnect happen in background.
When this option is not active or you are using another viewer you need to manual reconnect again.

It's implemented this way..sorry
