Run Bokeh on AWS EC2 server and get a blank page. No error messages

I am trying to delay my Bokeh server with AWS. It runs fine locally, but on my Linux EC2 it generates a blank webpage while no error messages are shown. My guess is that the EC2 does not meet the environment requests to run the interactive plots. Anyone has experience in deploying Bokeh with AWS? Do I need to install something for the plots to show? Thanks, Thank you guys for the responses. Here is what the log says, which I couldn't tell the problem: 

2016-12-29 17:52:39,665 Starting Bokeh server version 0.12.3

And the console log says:

Failed to connect to Bokeh server Error: Could not open websocket

Not sure on your exact details (i.e amazon instance type, linux disto etc..). If this solution does not work for you, you will need to provide more info.

Here is the process i took to set up a test linux instance:

  • Launch a Amazon Linux AMI 2017.03.1 (HVM) instance, which is
    running redhat.
  • Complete the installation for python 3.6 and bokeh 0.12.5
  • Lastly allow https access through the relevant amazon security group.

If you launch a bokeh server, and try access it on your local machine and it is appearing blank, check the bokeh server log. Mine appeared with this message : "Refusing websocket connection from Origin 'http://52.65.113.185:5006'; use --allow-websocket-origin=52.65.113.185:5006"

The solution is therefore to launch your bokeh app with the command: "bokeh serve --allow-websocket-origin=52.65.113.185:5006"

Or more generally. "bokeh serve --allow-websocket-origin={server_ip}:5006"
