Hi Chris

That's your VNC viewer sending a SYN packet

> win 0

And your server sending a RST (Reset) packet - aka "no application is
bound to this port"

Are you sure your VNC server is on screen 0?

Try another screen number (eg screen 1 which is port 5901)

Or run "netstat -aevpn|grep -i vnc" to find out which port it is bound to.

Kind Regards,
