Why do I get an "Access denied to VNC Server; please sign in to connect" error message when trying to connect to a RealVNC Server?


When trying to connect to a RealVNC Server using a cloud connection you may see the following error:


Why does this happen?

This message means that your RealVNC account has been signed out of RealVNC Viewer. This will happen if you have recently changed the password for your RealVNC account, for example.

You can check why this has happened by clicking the red cross next to your name in the top right of RealVNC Viewer:


Alternatively, you may be trying to connect to a device in your Address Book that you no longer have permission to discover. To check this, log in to the RealVNC Connect Portal's Device Access -> Computers page and find the computer in the list and check if "discovery is restricted". If you do not have team management permissions, please contact a Manager, Admin or Owner of the Team instead.

How do I resolve this?

To resolve the issue, click Sign in again and enter your RealVNC account credentials. Once you see a green tick/check mark in the top right next to your name, try connecting to the RealVNC Server again.
