AWS EC2：SSH 工作，但我无法使用我的 VNC

Question

I am running a Linux EC2 instance with TigerVNC viewer. This has worked for about six months until my EC2 instance recorded an error and I had to stop it from the Instance Console. I have restarted, but am now unable to access the GUI. SSH access from the console works and I can run commands in the terminal. I have checked the 'vncserver:1' command and am told that a VNC server is running, but when I open TigerVNC it crashes before asking for a password with the terminal error 'channel 3: open failed: connect failed: Connection refused'. Has anyone encountered a similar problem?

Answer 1

After more digging, the solution is to remove an X11 file. The following line in the terminal after using the ssh worked 'rm -rvf /tmp/.X11-unix/X1'.
