VNC Viewer “The connection was refused by the computer”

VNC Viewer “The connection was refused by the computer” error will prevent you from accessing a remote desktop due to an issue connecting with the remote host when you try to connect through VNC (Virtual Network Computing). The error often occurs when the VNC Server is either not running or not running on the specified port.

How to fix VNC Viewer “The connection was refused by the computer”

Getting the "VNC Viewer connection was refused by the computer" error can be really frustrating. The good news is that you can often fix this problem by trying a few simple solutions. Here, we'll give you three options to help you get past this issue.

Solution 1. Ensure the VNC Server is running

When encountering the "The connection was refused by the computer" in VNC Viewer, the first step is to confirm that the VNC Server is indeed running on the remote computer. Here's how you can do it:

• Check the remote computer: Log in to the remote computer using another method (like SSH or physical access) and ensure that the VNC Server software is installed and running. You can typically find VNC Server in your system tray or as a background process.
• Restart VNC Server: If the VNC Server is not running, try restarting it. This can often resolve the issue. You can do this through the VNC Server application or through terminal commands, depending on your operating system.

Solution 2. Configure VNC Server to use specified port

The default VNC port is 5900. Double-check that the VNC Server is set up to use the correct port. If you're making a direct connection and have chosen a port other than the default VNC port (which is 5900), make sure the VNC Server is configured to use the port you've specified.

Open Options in the VNC Server. Then, under Connections, check the port number behind Allow direct VNC connections over TCP and UDP. If you have specified a port other than the default 5900, change 5900 to the specified port.

Solution 3. Try a VNC alternative

If the first two solutions don't resolve the issue, it might be worth considering a VNC alternative remote desktop solution. This highly recommended option is AnyViewer. AnyViewer is a popular free remote desktop software that's known for its ease of use and reliability.

Besides, AnyViewer has the following advantages over VNC:

• Remote control features: AnyViewer provides advanced remote control features, including file transfer, remote sound, drag-and-drop file sharing, and even the ability to reboot the remote computer in safe mode. VNC offers basic remote control features but may not have as many advanced features as AnyViewer.
• Security features: AnyViewer emphasizes security and offers features like end-to-end encryption and two-factor authentication for added security. VNC also prioritizes security but may have fewer security features compared to AnyViewer.
• Screen sharing feature: AnyViewer includes built-in features for screen sharing. VNC primarily focuses on remote desktop access and control.

Starting with AnyViewer is a breeze. Here's how to get going:

Step 1. Begin by installing AnyViewer on your preferred devices.

Step 2. Lay the foundation by registering and logging in with the same account on both devices.

Step 3. On your local device, find the target remote computer listed under Devices, and effortlessly initiate connections using the convenient One-click control feature.
