No images in WebTiles

I am trying to run my own WebTiles server. Currently, I have the server up and running. However, there are no tile images. The UI loads properly. I can navigate to the URL for the images and access them properly. I am using an Ubuntu 16.04 LTS 64-bit server. Python version is 2.7 and Tornado version is 4.5.3.

Here is the relevant log dump:
  Code:

Re: No images in WebTiles

I don't know anything about this particular error, but webtiles doesn't work with tornado 4. You'll need to manually install tornado 3, I think any instance of 3 will do (I have 3.2.1 installed for testing), this is documented in the README in the webserver folder.

Re: No images in WebTiles

I have no idea how I missed that in the documentation. Going back to look at it now, it's obvious. Thank you for your help. I downgraded Tornado, and now everything works properly. For the benefit of anyone else having this problem, the latest version of Tornado 3.X is Tornado 3.2.2 and can be installed by issuing
  Code:
sudo pip install tornado==3.2.2
