I'm trying to install VNCServer on my VM box in Google Compute Engine (GCE), but it was not successful. 

I have followed the steps given in [this article](https://medium.com/@francesc/linux-gui-on-the-google-cloud-platform-800719ab27c5).

But still unsuccessful. I get the following error: 

```
"Time Out Waiting for a response from the host computer"

```

Can someone please let me know what's wrong here?
