Introduction
Virtual Network Computing (VNC) is a useful and popular remote access technology that allows users to access resources hosted in local machines or other cloud services. It is a great way for busy professionals and small businesses to collaborate on critical tasks, regardless of their geographical locations.
However, VNC servers can sometimes fail to listen for cloud connections, making it difficult to gain access to the required resources. This article aims at providing step-by-step guidelines on how to troubleshoot VNC server not listening for cloud connections.
Disable firewall
Firewalls are implemented as a security measure and may block incoming and outgoing requests, including those coming in from the cloud. If the VNC server is not listening for cloud connections, you should disable the firewall and check if the issue is resolved.
Windows Firewall can be disabled using the Control Panel. Go to Control Panel -> System and Security -> Windows Firewall -> Turn Windows Firewall on or off, and select the option ‘turn off Windows Firewall’ for both domain and private networks.
Additionally, you should ensure that your VNC server application also has its firewall enabled. Most VNC servers, such as TightVNC and UltraVNC, have their own output ports. Make sure that these ports, as well as the necessary protocols, are enabled in the server’s firewall, for both private and public networks.
Check server settings
Next, check if your server settings are configured correctly. Check if the connection type is set to cloud. Also, make sure that the port mapping is enabled and is set to the appropriate protocol. You should also check if the port number is configured correctly and there are no blocks on the proxy server.
Configure the VNC server
Make sure that you have the right version of the VNC server installed on your machine. You should configure the VNC server in order to be able to access it from the cloud. Consult the manual of the VNC server for instructions.
Restart the server
If none of the above steps work, try restarting the server. Make sure that all required ports are enabled and configured correctly. Once the restart is completed, check if the issue has been resolved.
FAQs
What is VNC?
Virtual Network Computing (VNC) is a tool that allows remote access to resources hosted on a local machine or other cloud services. It is commonly used by remote workers, developers, and small businesses to collaborate on important tasks from different locations.
How do I check if VNC server is listening to the cloud?
You can check if the VNC server is listening to the cloud by logging into the server-side or admin panel. Check the settings of the server to make sure that the connection type is set to cloud, port mapping is enabled, and the port number is configured correctly.
What should I do to access VNC from the cloud?
You need to ensure that the VNC server is installed on your machine and is configured properly for cloud access. In addition, check that all the necessary firewall ports and protocols are enabled and configured correctly for both the VNC server and your local machine.
How can I access the admin panel of VNC?
To access the admin panel of VNC, open the VNC server application and log in with the administrator username and password (if applicable). Once you are in the admin panel, you can check the settings of the VNC server and make sure that the connection type is set to cloud.
How can I disable my Windows Firewall?
You can disable Windows Firewall by going to Control Panel -> System and Security -> Windows Firewall -> Turn Windows Firewall on or off, and selecting the option ‘turn off Windows Firewall’ for both domain and private networks.
