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.

Cloud connections

Have you checked the most common reasons?
Are you signed in to RealVNC Viewer on the device you want to control from?
Are both endpoints connected to the Internet, and able to communicate with RealVNC services?
Is RealVNC’s connectivity service working?

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 192.168.5.127:80 for port 5980, and ::<full-number> for all other ports, for example 192.168.5.127::80 for 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?

If you have an eligible subscription, please contact Support.
