Negotiate Protocol Version ...

Post by atenasinfo »

I'm testing the ChunckVNC and am quite happy with this tool, only been bothering happens when = "Negotiate Protocol Version ..."

Connect to the client = vncserver, I get "Negotiate Protocol Version ..." and this message in the Viewer is infinite.

Is installed on the client side as InstantSuport the Service, and that I need to go back to work on the control panel and Restart the Service uvnc ...

Alternatives already executed and the problem continues.
1 - You have disabled firewalls both sides.
2 - I removed the encryption on both sides Viewer and Server.

Repeater is configured so.
Door open and configured = 5901 and 5500.

Anytime I see this problem it's when encryption is enabled on both sides, but the encryption plugins don't match. Not the keys, but the actual plugin file itself.

But I connect ! ! !

I'm using version 3.1.1 ChunckVNC , repeater108 , SecureVNCPlugin.dsm identical on both sides , and connect many times , after some connections the problem appears out of nowhere , there is another file encryption ? has some secret more specific ? Because ChunckVNC compiles the installer leaving both sides ready to Server and Viewer , I am urging the Client as a Service !

The issue I've seen prevents any connection from being established so it appears you're running into something else. Sorry :(
