I'm receiving the error "Connection Timed Out" (10060)"Connection timed out" indicates that no response was received from the specified IP address, even to reject the connection.
It usually indicates a misconfigured router or firewall. If you are running any firewall software on the VNC Server computer, please either disable it or configure it to allow access on port 5900 (See related question).
You should also check your port forwarding rules to ensure that you are forwarding port 5900 to the correct internal IP address (See related question).
Finally, you should check that you are entering your router's external IP address when connecting with VNC Viewer.
You can test if your VNC Server is accessible externally by going to this test webpage from the VNC Server computer:
You can also locate your router's external IP address from this page.
