WinVNC lost connection to repeater

[biware-repo]

In configuration WinVNC with Repeater and VNCViewer the WinVNC lossing connection to repeater.

In WinVNC is added Host and client ID and connection is created to Repeater (it is visible in Repeater Stats Waiting servers).

After create session with VNCViewer the client from WinVNC is lost - closed. Session is working, but client ID is not visible after session finished. It is not reconnected.
It does not matter whether it is Mode 1 or Mode 2. It is innevitable to add client id again.

All settings are default except IP addreses valid to environment.

So everything is working until session is created to station with WinVNC server.
