Can't Connect

Post by Jelly232 »

1.4.2.0

Having an issue with VNC Viewer where I am able to connect to all other devices except for a single one. When I type in the IP address it attempts to connect but then gives me a message saying "Can't connect to server". I also can't even ping it. Any ideas?

LAN WAN ?

It can be a routing issue or a firewall issue or ...

If local, try to disable firewall for a test, if it works, activate back and add vnc as exception.
If it's a routing issue.. can't help
