itself does not give an adequate description of the actual problem. However, it is most often caused by one of the vnc session closed unexpectedly following: Your "Hosts" filter has been deleted, or mis-configured. The "Hosts" parameter tells VNC Server which IP addresses are allowed to connect to it, and by default it is configured to allow all IP addresses. If vnc server status you've re-configured it, or deleted it, VNC Server will refuse all connections. Your RSA private key is missing. This is a rarer issue, but it does happen. The RSA private key is essentially a "hand-shake" between the VNC Server and VNC Viewer computer. The computers will know each other by RSA private key, and IP address, so that if a malicious user attempts a "man in the middle" attack, you'll have some warning.

Resolution Open up the VNC Server status, and enter the Configuration. Under the "Expert" tab, find the "Hosts" parameter. By default, it should simply contain a plus symbol "+", which denotes that connections will be accepted from all IP addresses. If the RSA private key has been deleted at either end of the connection, it can cause this problem. The RSA private key is stored in the registry of your computer. The easiest workaround, would be to force the generation of a new key. You can do this by running the folllowing command on the VNC Server computer: vncconfig -service -generatekeys If you are using Windows Authentication to log on to VNC Server, please also check that the Windows Event log is not full.

SiriusBer Level 1 (0 points) Q: VNC connections closed unexpectedly After some of the latest upgrades in OS X Lion when computer goes into sleep mode some connections doesn't work properly. Web Server, SSH, mail server (if any) work fine but it is impossible to remote control the computer via VNC. When trying to connect to the computer once in sleep mode with VNC viewer or similar and after the user and password submmision you get the "The connection closed unexpectedly" error and it's only possible to remotely connect to the computer when manually wake up the machine, making useless the remote control service.It seems that there's a lot of people with the same problem, so, how can we fix this issue? anyone know?Thanks in advance iMac, Mac OS X (10.7.4) Posted on Jun 1, 2012 5:52 AM I have this question too Close Q: VNC connections closed unexpectedly All replies Helpful answers Page 1 Next by BDAqua, BDAqua Jun 1, 2012 11:40 AM in response to SiriusBer Level 10 (123,960 points) Jun 1, 2012 11:40 AM in response to SiriusBer Just wondering, in System Preferences>Energy Saver>Options, what "Wake" things are checked there?
