Please check the following:
- Is the remote computer powered on and awake (that is, not asleep or in hibernation)?
- Is RealVNC Server running on the remote computer?
- Is RealVNC Server licensed?
RealVNC Server should be functioning correctly if there is a green tick (and no error messages) displayed in its Status dialog:
See this page for a full list of error messages you may see as a connecting user.
- Have you ensured the subscription applied to RealVNC Server includes direct connections?
Have you entered the remote computer’s IP address or hostname into RealVNC Viewer correctly, including a port number if required?If RealVNC Server is not listening on port 5900, enter
:<1-99>for ports in the range 5901-5999, for example
192.168.5.127:80for port 5980, and
::<full-number>for all other ports, for example
192.168.5.127::80for port 80.
If you’re connecting over the Internet, have you entered RealVNC Server’s public rather than private network address?
If you’re connecting over the Internet, have you configured the remote computer’s firewall and router properly?
Still can't connect?
If you have an eligible subscription, please contact Support.
