Encryption Pluging

Post by MarciaM »

I installed 1.1.9 and SecureVNC most recent version. It worked for several days but now I am getting the error message
You have specified an encryption plugin, however this connection is unencrypted. I have tried uninstalling and reinstalling an still no solution. The machines are Windows XP, Windows & and Windows 2008. Help.

The viewer has the plugin selected, but the server is sending his data unencrypted.
Verify the server site to see if the plugin is still selected.

This look stange, if the server has the plugin set then the server is using encryption, but the viewer connect to a
non encrypted server. Plugin is working else you can't configure it.

Are you sure that you are connecting to that server instance ?
It's always possible that you have 2 versions of vnc installed and you connect to another version.
Does the systray icon become yellow during connection ?
