Subject: Connection has been gracefully closed

 

Hi

 

I have just installed tightvnc 2.8.85 on two Windows computers, one running
Windows 10 and the other Windows 11.

 

I have not problem using Server on the Windows 11 computer and Viewer on the
Windows 10 computer, but I can't get it to work the other way round.

 

If I try to use Viewer on the Windows 11 computer and select the target
computer I can enter a password but it immediately goes to a window saying "
Connection has been gracefully closed".

 

Here is the Viewer logfile from the Windows 11 computer:

 

[ 6192/ 2632] 2025-09-13 20:01:27 - Init WinSock 2.1

[ 6192/14172] 2025-09-13 20:01:30 - Protocol stage is "Connection

[ 6192/ 2632] 2025-09-13 20:01:39 - Shutdown WinSock

 

Is the error with the Security type? How do I change this?

 

I'm not familiar enough with the protocol to understand this, so I'd be very
grateful if anyone could advise.
