Reasons for Connection Refused
The "connection was refused" error with VNC Viewer is irritating and common. Understanding this problem's causes is essential to solve it. Here are some common causes:
1.VNC Server Not Running
A common reason for connection refused is that the VNC Server is indeed not running on the remote computer. Despite its simplicity, this issue must be addressed. The remote PC must have a VNC server installed and running. If the server stops or doesn't respond, check it.
2.Firewall Blocking the Connection
Firewalls protect, but they can accidentally block legitimate connections like VNC Viewer. Allowing VNC traffic requires firewall configuration. Please ensure that both the host and remote computers have the VNC server listed as an exception in their firewalls. You can connect through the default port 5900 or other VNC server configurations.
3.Incorrect IP Address or Port
To establish the connection, it is necessary to enter the IP address or the port correctly. Typically, VNC servers utilize Port 5900. However, it is possible to change it, which may require further clarification. Please ensure that the IP address and port settings of your VNC Viewer and the remote computer are configured correctly to be on the same network.
4.Configuration Issues
Sometimes, it is necessary to ensure the VNC server is set up correctly. Ensure the server is set up to use the right settings and protocols.
5.Network Issues
Your connection request could be declined if the remote computer is part of a different network or there are network problems. Ensure that both computers are connected to the same network or that you use a VNC Connect cloud service for remote access.
6.Version Compatibility
It's possible that using an older version of VNC Viewer or VNC Server may cause compatibility issues. Please consider upgrading the VNC server to a newer version from RealVNC or updating your VNC Viewer. Occasionally, a legacy VNC server may decline a connection from a more recent client.
By understanding these common issues and how to address them, you can resolve the error message when trying to connect and successfully connect to your remote computer using VNC Viewer.
