On a regular basis I'm getting amessage when trying to connect to server by VNC

'Error creating local image of screen'.

After that I don't have a connecting to the server.

If I use the stand alone RealVNC viewer it works fine.

Any help as to what's wrong?

Hi,

which VNC server are you using?
If it is Real VNC, please set the server to "Allow legacy clients" and try again.

Hope this helps.
