vnc connection closed unexpectedly

这个问题通常是由于VNC服务器或客户端连接超时或出现网络问题导致的。以下是一些可能的解决方法：

1. 检查网络连接并确保VNC服务器和客户端都在同一局域网内。
2. 检查VNC服务器设置并确保连接超时时间足够长。
3. 尝试使用不同的VNC客户端应用程序进行连接。
4. 确保防火墙设置允许VNC连接通过。
5. 如果您正在使用加密连接，请检查SSL证书是否过期或无效。
6. 升级VNC服务器和客户端软件版本，以确保没有已知的错误或漏洞。

如果您仍然无法解决问题，请尝试在VNC客户端应用程序中启用调试日志，并查看是否有任何错误或警告消息。这有助于更好地了解问题的根本原因并确定解决方案。

vnc中The connection closed unexpectedly.

The "connection closed unexpectedly" error message in VNC usually means that the VNC client was unable to connect to the VNC server or the connection was lost for some reason. Here are a few things you can try to resolve the issue:

1. Make sure that the VNC server is running and is accessible from the network. You may need to check your firewall settings to ensure that the necessary ports are open.

2. Check the connection settings in your VNC client to ensure that they are correct. Make sure that you are using the correct IP address or hostname and port number to connect to the VNC server.

3. Try restarting the VNC server and/or the VNC client to see if that resolves the issue.

4. If you are using a VPN or a proxy server, try disconnecting from it and connecting directly to the network to see if that resolves the issue.

I hope this helps. Let me know if you have any other questions.

vnc the connection was refused

"Connection refused" error message usually indicates that the VNC server is not running or is not configured to accept connections from your computer.

Here are a few things you can try:

1. Check if the VNC server is running on the remote machine. You can do this by logging into the remote machine and running the command `vncserver -list`. If the output shows a running VNC server, then you can proceed to the next step. If not, you may need to start the VNC server by running the command `vncserver`.

2. Check if the VNC server is configured to accept connections from your computer. You can do this by checking the VNC server's configuration file, usually located at `/etc/vnc.conf` or `/etc/vnc/xstartup`. Make sure that the file has the correct settings for allowing remote connections.

3. Check if there is a firewall or network issue blocking the connection. Make sure that the VNC server's port (default is 5900) is open and not blocked by any firewall rules or network configurations.

4. Try connecting from a different computer or network to see if the issue is specific to your machine or network.

If none of these solutions work, you may need to seek further assistance from the VNC server's support team or documentation.
